Two previously undeformed cylindrical specimens of an alloy are to be strain hardened by reducing their cross-sectional areas (while maintaining their circular cross-sections). For one specimen, the initial and deformed radii are 15mm and 12mm, respectively. The second specimen, with an initial radius of 11mm, must have the same deformed hardness as the first specimen. Compute the second specimen’s radius after deformation

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.
