It is known that a brass alloy has a yield strength of 275 MPa, a tensile strength of 380 MPa and a modulus of elasticity of 103 GPa. It is determined that a 12.7 mm diameter and 250 mm long cylindrical sample made of this alloy is elongated by 7.6 mm under the tensile stress effect. Based on this information, is it possible to calculate the magnitude of the load required to generate the said elongation? If possible, calculate, if not, explain why.

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.
