Answer:
The mechanical properties are those which affect the mechanical strength and ability of a material to
be molded in suitable shape. Some of the typical mechanical properties show huge applications in
space and automobile industries. These properties are associated with the capability of the materials to
resist mechanical forces and load and they are measured in terms of the behavior of the material when
subjected to a force. Mechanical properties may be determined to provide either design data for the
engineer or as a check on the standard of raw materials [1]. Mechanical properties may be changed by
heat treatment process and the working temperature. Mostly, the strength, toughness and hardness of
materials are to be measured after the metal forming process [2]. The main objective of the paper is to
give the overview of the importance of mechanical properties of the materials, testing. This paper,
includes the concepts of strength, plasticity, malleability, stiffness, elasticity, brittleness, ductility,
toughness, resilience, fatigue, creep and shown how improper understanding of properties can lead to
have confusion.
