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.

Question

1) Drawing: Consider a cylindrical rod fabricated from a linear strain hardening material with a
constitutive relationship of o=2000 + 20000 € (where o is in psi). The rod is drawn into a wire. If the
