Materials in Engineering - Essay ExamplePracticing engineers have to understand the specific characteristics of these materials in order to make the well-nigh appropriate selection for the job on hand.Engineering materials are of many types metals (ferrous and non-ferrous), plastics, polymers, ceramics, glass, cement etc. The most extensively used materials for engineering are of trend metals followed by cement, plastics and ceramics. Different engineering disciplines like mechanical, civil, electrical, space engineering, electronics etc. have to use these materials for building their intended products. Such 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 problem, given the different situations and the vast array of available materials. To bear this problem and make the most appropriate selection, design engineers have to match the application needs to the ch aracteristics of the materials.A defined set of load conditions may implore completely different materials depending upon the application of the item e.g., in surface transport vehicles, ocean going liners or in space crafts. Design engineers select materials, depending upon their properties and suitableness 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 mark (like St 42W) may be quite suitable for a railroad 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 another example, electronic components used in TV sets are specifically tropicalized for suitability of operation in hot countries. Thus, it is ess ential to understand the vast variety of
