Materials in Engineering - Essay ExamplePracticing engineers have to understand the particular characteristics of these materials in order to make the most appropriate selection for the job on hand.Engineering materials ar of many types metals (ferrous and non-ferrous), plastics, polymers, ceramics, glass, cement etc. The most extensively used materials for engineering are of course metals followed by cement, plastics and ceramics. Different engineering disciplines like mechanical, civil, electrical, berth engineering, electronics etc. have to use these materials for building their mean products. much(prenominal) products operate or exist in a vast variety of situations, and it is this variety that determines which materials are to be used where. The selection of materials poses a paradox, given the different situations and the vast array of available materials. To confront this problem and make the most appropriate selection, design engineers have to match the application nee ds to the characteristics of the materials.A be set of load conditions may demand entirely different materials depending upon the application of the item e.g., in draw close transport vehicles, ocean going liners or in space crafts. Design engineers select materials, depending upon their properties and suitability for the intended purpose. This is because, while the stresses and strains may be similar, the behavior of the material in the different situations can be completely different. A normal structural steel (like St 42W) may be quite suitable for a railroad track car in Latin America, but is unsuitable in cold regions like Russia, where it may be subject to temperature variations of +35 to -35 deg. Celsius. A ferritic stainless steel may be unsuitable in space engineering while the same may be quite adequate for kitchenutensils. Or to cite some other example, electronic components used in TV sets are specifically tropicalized for suitability of operation in impatient cou ntries. Thus, it is essential to understand the vast variety of
