Hardness tests are performed more frequently than any other mechanical test for several reasons: (Choose all that apply): Other mechanical properties can be estimated from hardness data such as tensile strength The test is simple and inexpensive The test is nondestructive, which means that the specimen is neither fractured or excessively deformed after the test Testing apparatus is relatively expensive

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
