Airplanes And Aircraft Engineering Essay

Airplanes And Aircraft Engineering Essay Aircrafts are capable of flight using forward motion that generates lift as the wing moves through the air. Airplane is propelled by a screw propeller or a high-velocity jet, and supported by the dynamic reaction of the air against its wings. There are many components of an airplane however the essential components are a wing system to sustain it during flight, tail surfaces to stabilize the wing, movable surfaces to control the attitude of the machine in flight, and a power plant to provide the thrust to push the craft through the air. An enclosed body which is known as the fuselage houses the crew, passengers, and cargo, as well as the controls and instruments used by the navigator. An airplane also requires a support system when it is at rest on a surface and during takeoff and landing. Airplanes have different shapes and sizes depending on the purpose, but the modern airplanes have some features in common. They are fuselage, tail assembly and control surfaces, wing, power-plant and landing gear. In this report the prime focus is on the Prime components of the aircraft assuring structural integrity while meeting requirements for optimum operational performance of an aircraft. The empennage is also known as the tail is the rear part of the aircraft. Usually it includes the stabilizers, rudder and elevator as many other components as seen below.. It is constructed depending on the aircraft for example in fighter jets it may be constructed around the exhaust nozzle. In commercial aircrafts the empennage is built from the cabin pressure-cone and may contain the Flight Data Recorder (black box), Cockpit Voice Recorder and the pressure out-flow valve. There is another design which does not require an elevator. In this design there is a one-piece horizontal stabilizer that pivots from a central hinge point, such a design is known as a stabilator. 2. Wings: As we can see below is a wing. Wings are airfoils attached to each side of the fuselage and are the main lifting surfaces that help the airplane during flight. There are great variations in the wing designs, sizes, and shapes used by the various manufacturers. Each of these specifications fulfils a certain need with respect to the performance for an airplane. Wings may be attached at the top, middle, or lower portion of the fuselage and are referred to as high-, mid-, and low-wing, respectively. The number of wings may vary. Monoplanes contain a single set of wings while those with two sets are called Biplanes. The principal structural parts of the wing are SPARS, RIBS, and STRINGERS. These are reinforced by trusses, I-beams, tubing, or other devices, including the skin. The wing ribs determine the shape and thickness of the wing (airfoil). Attached to the rear, or trailing, edges of the wings are two types of control surfaces referred to as ailerons and flaps. http://khup.com/view/2_keyword-design-of-aircraft-rib-structure/aircraft-structure.html 2.1 Spars 2.1.1. Definition: The spar is the main structural member of the wing, in a fixed-wing aircraft, running span wise at right angles to the fuselage. There may be more than 1 spar or none at all. 2.1.2 Uses: Fight loads and the weight of the wings whilst on the ground is carried by spars. Spars are also used in aerofoil surfaces such as the tail plane, fin and serve a similar function, although the loads transmitted may be different. 2.1.3. Loads: Upward bending loads from the wing lift force that supports the fuselage in flight. Downward bending loads due to the weights acting. Drag loads dependent on airspeed and inertia. Rolling inertia loads. Chordwise twisting loads due to aerodynamic effects at high airspeeds. 2.1.4. Materials: Wooden construction Early aircraft used spars carved from solid Spruce or Ash. Wooden spar types have been used and tried with such as spars which are box-section in form; or laminated spars which are laid up in a jig, and compression glued to retain the wing dihedral. Wooden spars are still being used in light aircraft such as the Robin DR400. Metal spars A common metal spar in a general aviation aircraft generally consists of a sheet aluminium spar web, with L or T -shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads. Tubular metal spars The German Junkers J.I armoured fuselage ground-attack sesquiplane of 1917 used a Hugo Junkers -designed multi-tube network of several tubular wing spars, placed just under the corrugated duralumin wing covering and with each tubular spar connected to the adjacent one with a space frame of triangulated duralumin strips riveted onto the spars. Advantages Gives substantial increase in structural strength at a time when most other designs were built with wood-structure wings. Geodesic construction In aircraft such as the Vickers Wellington, a geodesic wing spar structure was employed which had the advantages of being lightweight and able to withstand heavy battle damage with only partial loss of strength. Composite construction Nowadays aircraft use carbon fibre and Kevlar in their construction, ranging in size from large airliners to small aircraft. Companies have employed solid fibreglass spars in their designs but now often use carbon fibre in their high performance gliders such as the ASG 29 Advantages The increase in strength and reduction in weight compared to the earlier fibreglass-sparred aircraft allows a greater quantity of water ballast to be carried. 2.1.5. Disadvantages: The wooden spar has a danger of the deteriorating effect that atmospheric conditions, both dry and wet, and biological threats such as wood-boring insect infestation and fungal attack can have on the wooded spars; consequently regular inspections are often mandated to maintain airworthiness. Similar disadvantages on metal spars limit their use. 2.2 Ribs 2.2.1. Definition: In an aircraft,  ribs  are forming elements of the structure of a  wing. Ribs are attached to the main  spar, and by being repeated at frequent intervals they form a skeletal shape. Usually ribs incorporate the  airfoil  shape of the wing. They are the cross-section shape of a wing. The ribs can be classified according to the types of load acting on it. Lightly loaded ribs are subjected to aerodynamic loads while a rib is subjected to concentrated forces transferred from primary points is considered as moderately loaded rib. 2.2.2 Function: Maintain the sectional shape of wing box. Function as panel breakers for stringers. Provide support for attachment of other systems. Distribute locally applied air pressure loads. 2.2.3. Stiffness: The ribs contribute little to the overall stiffness of the wing box and also carry little of global bend and twist loads acting on the wing. 2.2.4. Loads: Loads acting on the ribs are of three types: Loads transmitted from the skin-stringer wing panels. Concentrated forces transmitted to the rib due to landing gear connections, power plants nacelle connections, etc Body forces in the form of gravitational forces. Inertia forces due to wing structural mass. 2.2.5. Materials: Ribs are made out of wood, metal, plastic, composites, foam. Carbon reinforced composites (CFC) or Carbon Fibre Reinforced Plastics (CFRP) are used extensively in aircraft structures as they give high stiffness and strength with lower weight. 2.2.6. Advantages and Disadvantages: Wooden ribs are subjected to atmospheric deterioration. http://khup.com/view/2_keyword-loads-acting-on-ribs/report-5.html 2.3. Stringers or Longerons Interior of a Boeing/ Stearman PT-17 showing small channel section stringers. 2.3.1. Definition: A longeron  or  stringer  or  stiffener  is a thin strip of wood, metal or carbon fibre, to which the skin of the aircraft is fastened. Longerons are attached to  formers  in the case of the fuselage, or  ribs  in the case of a wing, or  empennage. In early aircraft, a fabric covering was sewn to the longerons, and then stretched tight by painting it with  dope, which would make the fabric shrink, and become stiff. 2.3.2. Properties: Longeron and stringer are used interchangeably. If the longitudinal members in a fuselage are less in number (usually 4 to 8), they are called longerons. The longeron system requires that the fuselage frames be closely spaced (about every 4 to 6 in/10 to 15 cm). If the longitudinal members are numerous (usually 50 to 100) then they are called stringers. In the stringer system the longitudinal members are smaller and the frames are spaced farther apart (about 15 to 20 in/38 to 51 cm). Longerons are of larger cross-section when compared to stringers. 2.3.3. Advantages: On modern aircraft the stringer system is more common because its more weight efficient despite being complex to construct and analyze. Some aircraft, use a combination of both stringers and longerons. The stringers carry bending moments and axial forces. They also stabilize the thin fuselage skin. 3. Power Plant: A power plant consists of propeller and engine.   The main function of the engine is to supply power to run the propeller. It also generates electrical power, provides vacuum source for flight instruments, and provides a source of heat for the pilot and passengers. The engine is covered by a cowling, or in some airplanes, surrounded by a nacelle. Its purpose is to streamline the flow of air around the engine and to help cool the engine by ducting air around the cylinders. The propeller on the front of the engine converts the rotating force of the engine into forward acting force called thrust that helps move the airplane through the air. 4. Landing gear: Every matter has its base on which it stands. The principle support of the airplane when parked, taxiing, taking off, or when landing is its landing gear. The most common type of landing gear consists of wheels, but airplanes can also be equipped with floats for water operations, or skis for landing on snow. The landing gear consists of three wheels two main wheels-tail wheels and a third wheel positioned either at the front or rear of the airplane-nose wheel, the design is referred to as a tricycle gear A steerable nose wheel or tail wheel permits the airplane to be controlled throughout all operations while on the ground.    5. Fuselage Fuselage is aircrafts main body and covers the majority of the airplane, it holds all other pieces of the aircraft together and other large components are attached to it. The fuselage is generally streamlined to reduce drag. Designs for fuselages vary widely. The fuselage houses the cockpit where the pilot and flight crew sit and it provides areas for passengers and cargo. Some aircraft carry fuel in the fuselage; others carry the fuel in the wings. 5.1. Types of Fuselage Structures: Truss Structure Geodesic construction Monocoque Shell Semi-monocoque 5.5.1. Truss Structure: This kind of structure is used in lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood-covered with plywood. 5.1.2. Geodesic construction: Geodesic structural elements used by during the wars, World War II, to form the whole of the fuselage, including its shape. In this multiple flat strip stringers are wound about the formers in opposite spiral directions, giving a basket-like appearance. This proved to be light, strong, and rigid and had the advantage of being made almost entirely of wood. Its redundant structure can survive localized damage without catastrophic failure. 5.1.3. Monocoque Shell In this method, the exterior surface of the fuselage is also the primary structure. A typical early form of this built using moulded plywood, where the layers of plywood are formed over a plug or within a mould. A later form of this structure uses fibreglass cloth impregnated with polyester or epoxy resin, instead of plywood, as the skin. A simple form of this used in some amateur-built aircraft uses rigid expanded foam plastic as the core, with a fibreglass covering, eliminating the necessity of fabricating moulds, but requiring more effort in finishing. An example of a larger moulded plywood aircraft is the de Havilland Mosquito fighter/light bomber of World War II. No plywood-skin fuselage is truly monocoque, since stiffening elements are incorporated into the structure to carry concentrated loads that would otherwise buckle the thin skin. The use of moulded fibreglass using negative (female) moulds (which give a nearly finished product) is prevalent in the series production of ma ny modern sailplanes. 5.1.4. Semi-monocoque. This is the preferred method of constructing an all-aluminium fuselage. First, a series of frames in the shape of the fuselage cross sections are held in position on a rigid fixture, or jig. These frames are then joined with lightweight longitudinal elements called stringers. These are in turn covered with a skin of sheet aluminium, attached by riveting or by bonding with special adhesives. The fixture is then disassembled and removed from the completed fuselage shell, which is then fitted out with wiring, controls, and interior equipment such as seats and luggage bins. Most modern large aircraft are built using this technique, but use several large sections constructed in this fashion which are then joined with fasteners to form the complete fuselage. As the accuracy of the final product is determined largely by the costly fixture, this form is suitable for series production, where a large number of identical aircraft are to be produced. Both monocoque and semi-monocoque are referred to as stressed skin structures as all or a portion of the external load (i.e. from wings and empennage, and from discrete masses such as the engine) is taken by the surface covering. In addition, the entire load from internal pressurization is carried (as skin tension) by the external skin. As stated above we are now familiar with the prime components of an airplane. Now let us get into detail, and understand the components such as the bulkhead, Frames, Ribs, Spars, Stringers (Longerons), and Skins. 5.2. BULKHEADS 5.2.1. Definition: A bulkhead is the physical partition that divides a plane or a fuselage into different classes or sections. Typically, a bulkhead is a wall but can also be a curtain or screen. In addition to separating classes from one another, i.e. business and economy, bulkheads can be found throughout the plane, separating the seats from the galley and lavatory areas. Bulkheads also contribute to the structural stability and rigidity of a craft. 5.2.2. Uses: 5.2.3. Loads: 5.2.4. Materials: 5.3. FRAMES 5.3.1. Definition: The airframe provides the structure to which all other components are attached. Airframes may be welded tube, sheet metal, composite, or simply tubes bolted together. A combination of construction methods may also be employed. The airframes with the greatest strength-to-weight ratios are a carbon fibre material or the welded tube structure, which has been in use for a number of years. 5.3.2. Uses: 5.3.3. Loads: 5.3.4. Materials: Material Selection Material Usage Advantages Disadvantages High strength unidirectional graphite/epoxy Spar caps High strength, low weight High cost, low impact resistance, difficult to manufacture High modulus  ±45 ° graphite/epoxy Skin (w/foam core), Shear web, Wing ribs High strength, low weight, low surface roughness, stealth characteristics High cost, low impact resistance, difficult to manufacture Aluminum 7075-T6 Bulkheads, Longerons Low cost, ease of manufacture, good sturctural efficiency Low strength, not weldable Stainless steel (AM-350) Landing gear Relatively low cost, high strength, corrosion resistance High weight Nickel (Hastelloy B) Nozzles and ducting Temperature resistance Low structural resistance Kevlar Internal armor High strength, low weight, high impact resistance High cost, difficult to manufacture

Reflective Essay on Fiction Writing :: Teaching Writing Education Essays

Reflective Essay on Fiction Writing I’ll be honest. I was worried about writing fiction up until I realized that fiction is just nonfiction exaggerated, nonfiction with a wider allowance for artistic merit, and nonfiction with the gaps filled in. And fiction doesn’t have to be as imaginative, in a fantasy sense, as I had thought. It’s still very real, or at least mine is. For the nonfiction essay, I wrote a string of memories, anything I could think of and that I could potentially expand upon in a longer piece, and I did this early on. For this fiction essay, I am doing something similar; I made a list of character types and wrote some sketches of ‘characters’ I’ve come across in my own life. I used one of these character types for my extraordinary scene, and then sought help from the king of making the ordinary extraordinary, William Carlos Williams, to fix the character in a scene. Using the character type worked for me this time because I was merely observing her; there was some distance, and I didn’t have to get inside her head so much. In general, though, I find that I shy away from the character types, at least for our assignments, because they require a lot of work on my part, and I didn’t have enough time to get to know them well enough to do them justice in a story. So I stuck to the characters I knew more ab out. For my short fiction, I worked off the framework of a story that I knew happened. But my knowledge of the event was very limited (it could be told in one sentence), so I filled in the gaps and made it fiction by telling my version of what might have happened. For the longer fiction, I worked off of something that one of my real life ‘characters’ said jokingly, but I built a fictional story around it being said in all seriousness. Overall, I’m happy with my extraordinary scene. I like the picture I created. It’s satisfying. I like it on its own, but I also wonder what more I could do with it. I think I could work with her character, maybe bring her up against some trouble. We discussed this in conference, but I really think that I should think up some trouble for my characters. I think I have developed and even embodied my characters well, but my stories don’t push any limits because they lack tension and urgency.

Nursing Essay

Introduction It is typically impossible to satisfactorily talk about a health facility without a thought of doctors and or nurses being a part of it. Even though these are two different personalities in terms of what their duties are, they all function towards a common good of restoring good health and therefore one can hardly function properly without the other. This piece is going to compare and contrast the nurse and a doctor in terms of their place in the health care system (roles, remuneration, social expectations and training). In terms of differences, the training that nurses receive enable them to function as general health practitioners who execute their functions to any population suffering from various forms of diseases like cancers, Communicable diseases or even HIV/AIDS. The doctors on the other hand are always trained in specific lines like pediatric, Gaenacology, Orthopedic, Optical medicine or general Surgery among others. In terms of training, it is always expected that nurses undergo a four year training during which the nurse is expected to have gone to the hospital set up and train on how to execute their expected roles. After the completion of this, one can easily qualify to work as a Registered Nurse so long as he/she passes this section as expected. This is quite the contrary with the training of doctors. While they are also supposed to undertake a clinical at the hospital set up during their first years of training, they normally have to apply and be admitted to a medical school after the first graduation (Prince, 2010). During this time it is expected that the doctor shall have gained more experience after graduating. This latter face is where the doctor is now expected to memorize the diseases, their prognosis, diagnosis and etiology among other factors in  detail. In most cases, the doctor normally takes most of his time giving opinion on what needs to be done and the diagnosis while the nurse mostly does what the doctor has said should be done. It is common to find that a nurse enjoys a very close relationship with patients than doctors who most of the time try to detach themselves. There is also a slight difference in times of the job demands where doctors always have to read a lot of books do research and compare notes with other practitioners as a way of offering updated care. The nurses on the other hand rely more on their experience since most of the works are routines. This is even explained by the various guidelines used across the nursing profession except for parts that have to be altered simply for purposes of cultural differences. Finally, it is also common knowledge that doctors are better than nurses in terms of remunerations. For instance, while it is expected that a registered Nurse will earn an average of about $57, 000 per an num, a registered doctor earns between $ 160, 000 – $ 240, 000 per annum (Coyle, 2011). Both the doctors and nurses also have certain common functions. It is for instance expected that both the registered nurse and registered doctors for instance have the responsibility to supervise all the juniors that work under them. Both doctors and nurses equally have the opportunity to work in various avenues including medical schools, private and even public hospitals. It is also important to note that both the nurse and the doctor are part of a common goal to restore good health in the sick population (Floyd, 2009). Without the doctor diagnosing, the nurse will not know the medications or medical interventions to undertake on a patient. The doctor on the other hand would not achieve his/her mission without the parts performed by the nurse. In conclusion, doctors and nurses are medical personnel that have interrelated work where one cannot function properly without the other especially in a large clinic set up. While they both work for a common goal, they have different responsibilities; something that makes them to seek different information. References Coyle, D.G. (2011).

Focault analysis essays The Manufacturing of an American Soldier: An Examination of the Indoctrination Process During the Gulf War at Fort Knox, Kentucky "As a soldier, you have accepted a solemn obligation to defend the ideals of freedom, justice, truth, and equality as found in The Declaration of Independence and the United States Constitution. Whether you are serving a single term or making a career of the military, your actions should never be contrary to the ideals and principles upon which this nation was founded." - Department of the Army, Soldier's Handbook (62) In February of 1991, Bravo Troop of the 5/15 Cavalry stationed at Fort Knox, Kentucky Training Facility performed a ritualized, ceremonial examination of its new recruits. The recruits arose at four a.m. and marched till eight to arrive at a small, secluded building surrounded by forest. The recruits stood in a single-file line facing the entrance of the building, eyes forward, feet shoulder width apart, hands folded in the small of their back. Approximately one hundred and twenty recruits stood peering through the lenses of their protective masks, watching fifteen soldiers enter the building. Once inside the building, the fifteen recruits stood at attention, fingers curled, thumb locked on second knuckle of the index finger, hands placed at their sides, heels together, feet splayed at a forty-five degree angle, stomach in, chin-up, eyes forward, in three lines, five recruits deep, facing the Drill Instructor. The room was filled with thick, white smoke. The only light ca me from a small fire burning on the cement floor at the drill instructor's feet.

Exposure to such high concentrations of CS gas produces a violent, bodi...

Marxism And Economic Theory Essays - Economic Ideologies, Socialism

Marxism And Economic Theory Essays - Economic Ideologies, Socialism Marxism and Economic Theory Human relationships have always been dynamic. Change and adaptability have gone hand in hand with the passage of time for human society. Systems have been developed to regulate, direct and control the resources of this society. The systems are referred to as governments and the resources as the populace or inhabitants and forces of production. A government must be dynamic in its nature reflecting the change in society. At times these systems have resisted the necessity to adapt with its components (Society) creating a deficit between the system and those it regulates. As the deficits develop, they cause instability, and could lead to revolution.1 Theories have been developed to explain the systemic phenomenon called revolution. This paper will discuss three modern theories and apply them to the English revolution of 1640. The first theory, developed by Carl Marx (Marxism), will address the economic evolution in English society. This theory will emphasize and explain how the shift from a feudal/mercantile system to capitalism affected English society. The second, called the Resource Mobilization Theory (RMT) developed by Charles Tilly, will explain how the English organizations (the Crown and the Parliament) effectively obtained, amassed and managed resources. Samuel Huntington's, "Institutional Theory", will argue that the existing government at that time was unable to incorporate the demands and personnel that the socio-economic changes created. Marxism was formulated in the 19th century. Carl Marx and his associate Frederick Engels observed the socio-economic changes that were transpiring in Britain. England was the dominant world power and had the largest industrialized economy during the 1800's. The development of the factory and the institution of the assembly line created a large demand for workers. This demand was satiated by migrating peasant from the rural areas in England and Ireland to developing urban centers. As these urban centers or cities evolved using industry as the economic backbone for the population, a large number of factory workers were accumulated to operate the machinery in horrid conditions. These workers, which would be termed as the peasantry under a feudal system, were now the working class or proletariat. They entered cities with hopes of bettering their lives and survival. Though revolution never took place in England during this period, it allowed Marx to study industrialization, urbanization and imperialism. The theory of Marxism has three basic concepts: historic materialism, forces of production and relations of production. Historic materialism is defined as a society's past performance and present capabilities of satisfying the basic means of life. Humankind's basic needs of eating, drinking and shelter need to be met properly. The forces of production (technology, capital, the infrastructure of society, etc.) are important for the simple fact of who ever controls them controls the society. The last aspect of Marxism, the relations of production, deals directly with the relationships between classes of people (the aristocracy, the middle-class and the working class).2 Marxism includes a predictive analysis of socio-economic structures. Using history, logic and the dynamic nature of humankind as guidelines, Carl Marx attempts to map out a sequence of events which will eventually lead to utopia (anarchy). In his work, Das Capital, Marx details the six steps. These steps are primitive socialism, feudalism, capitalism, socialism, communism and then anarchy. The evolution of the English economic system during the 16th and 17th centuries points to a shift from feudalism to capitalism. This shift is exemplified by the enclosures. The landlords began to fence their property in the common land areas. The "commons" were large plots of grazing and farmable lands that were used by both farmers and artisans. When the land-owners and manorial lords began to partition these lands the concept of private ownership of property was introduced to the socio-economic system.3 During the time period of the 16th and 17th centuries the crown's economic base began a gradual decline. This economic shrinkage came to a spearhead during the reign of Charles I. The monarchy favored a monopoly market system over a competitive one. The purpose for this position was for taxation and control of the profits. As the artisan and merchant populations increased, the policy of the crown began conflicting with economic growth. This created instability in three areas. First, the English

Depression and Care for the Elderly Essay Example | Topics and Well Written Essays - 1000 words

Depression and Care for the Elderly - Essay Example It is possible to have depression rated as higher because of the similarity of some of the symptoms between depression and dementia. Geriatric psychiatric studies have shown a relationship between prefrontal cortex function and successful treatment of geriatric depression1. Geriatric patients who had a positive result during depression screening were studied to determine the pharmacological impact on their recovery. 110 depressed geriatric patients (over age 60) were treated with medication after an assessment that tested the pre-frontal cortex function (to establish a baseline). After three months the study group was reevaluated and a correlation between higher pre-frontal cortex function and depression remission levels was made2. The study showed that depression in the elderly can be diagnosed and successfully treated. The study also showed a relationship between prefrontal cortex function and depression and may indicate a secondary way to identify depression in the elderly (especi ally non-verbal patients). Detecting depression in the elderly is no easy task because of the reluctance to self-report. In addition to the standard characteristics of depression (ie. insomnia, sadness, and loss of self worth), elderly patients may show signs of over concern about bodily aches and pains. Some symptoms of old age (loss of appetite and weight loss) are also symptoms of depression. Obviously, if one is diagnosed with depression and the treatment (medications and/or talk therapy) works, that would confirm the diagnosis. Appendix A contains a typical screening for depression in the elderly. Elderly that suffer from depression often don't take good care of themselves. As their self-care drops so does their compliance level when it comes to medication and diet. This group reports as having a higher incidence of suicide and suicidal ideation than the general population. Studies have shown that suicides in the elderly often use highly lethal methods and are successful more often than in the general population3. This same study found that 20% of elderly patients that committed suicide had seen their health care provider within the 24 hours prior to the suicide, 41% within a week, 75% within one month. This indicates that geriatric practitioners should screen for depression and suicidal ideation at each patient visit rather than a random screen or no screen at all. There is a higher incidence of depression among elderly that are caring for an elderly spouse4. These caregivers often feel older than their age. "Caregivers for impaired spouses experience a kind of distress that isn't easily measured," Kiecolt-Glaser says5. The caregiver's in the study died at a higher rate than other seniors who were not caregivers. These caregivers would benefit from a screening program targeting those who provide ongoing care to their spouse. Teaching and learning strategies need to be in place to deal with depression in the elderly. Both the elderly and their caretakers need to be informed about the causes and symptoms of depression and how to get appropriate care. They also need to understand that they need not feel stigmatized by the diagnosis. Once depression is diagnosed, treatment and education should begin. Because depression lasts longer in the elderly and can hasten death from an existing illness, treatment needs to begin as soon

Coca Cola Code of Business Ethics Essay Example | Topics and Well Written Essays - 1250 words

Coca Cola Code of Business Ethics - Essay Example This also reveals that the ethical system used by the company is based on duty, where all the stakeholders held by the code of ethics are expected to follow a specific duty. The company is guided by the Coca Cola code of business conduct, which is a set of, laid down rules for the administration of ethical and compliance matters (Coca Cola, 2011). An analysis of the Coca Cola COBC (the code) will reveal that it is applied in all levels of the company’s operations, and there is a framework for its administration. This analysis will focus on the administration of the code both within and outside the company by the employees, managers, and all other stakeholders covered by the code. This covers three main areas, integrity in operations around the world, integrity of service within the company, and integrity of service to other people (Coca Cola, 2011). The internal mechanisms for the code revolve around the expectations from the employees and managers, while the second section re volves around actions around the company. This includes actions that deal with financial matters information within the company, and the utilization of company assets. ... Coca Cola states that all employees in the company must always act with integrity, since it is one of the cornerstones of the companies operations (Coca Cola, 2011). The ethical standards set by Coca Cola indicates that all employees must act in accordance with the law and the code, and in case of any actions, the employees must always ask themselves if the action will break these two tenets. The employees are also advised to ask for guidance in case they doubt the ramifications of any of their actions. The managers of the company are also guided by the code, where the main factor is that they should promote a culture of ethics and compliance (Coca Cola, 2011). This means that the managers should always display appropriate conduct, and help their subordinates as much as they possibly can. The managers should ensure that the code is followed by all employees, which includes giving their help when needed. This is in addition to creating a conducive working environment for their employe es, and always preventing the violation of the code by any employees. The code also dictates that any actions that deem the provision of written approval should be handled by the local ethical officers present in all workplaces. The ethical conduct code promoted by the company is also focused on creating an ethical framework within the company itself, and from an analysis of the code, it is evident that this is settled. The COBC focuses on three parts in their code, dealing with company records, dealing with assets, and the use of available information (Coca Cola, 2011). The ethical code utilized by Coca Cola indicates that all stakeholders should always ensure that company records are accurate, which includes all financial information, quality reports, and all other records used by the
