5. The knowledge of engineering materials and their properties is of
great significance for all engineers of different disciplines. The
humans have grown with civilization. Several components are
required for producing the items which are used in day to day life.
ENGINEERING MATERIALSProperties Of Materials
Materials property is defined as a qualitative or quantitative
measure of response of materials to externally imposed condition
like forces and temperatures .
