The Influence of Materials Properties on Structural Form and Behaviour Essay

The Influence of Materials Properties on Structural Form and Behaviour - Essay Example As the discussion stresses  during the selection of materials to be used for engineering purposes, certain properties that include tensile strength, impact strength, as well as hardness is essential in indicating how suitable the selection for the material is, although the engineer has the obligation of ensuring that radiography together with other properties for the material are in line with required specifications.From this paper it is clear that  there has been an increase in popularity of plastics and polymeric materials in engineering. As much as these are inferior to majority of the metallic materials as far as temperature resistance and strengths are concerned, these have been used in corrosive environments as well as in other areas that require minimum wear, for example in small gear wheels that were initially manufactured from hardened steel, are currently produced from Teflon or nylon.  The performance of these materials is satisfactory; they are quiet and are in no n eed for lubrication. In this respect, therefore, prior to selection of material or even the designing of components, there is need for an individual to have sufficient knowledge of the process requirements, the limitations of operation like the non-hazardous and hazardous conditions, the continuous and the non-continuous operations, raw material availability together with the availability of spares and other alternate material.a
