In the figure, a solid copper rod with an expansion coefficient aB = 165.107-1 / °C is 20 mm in diameter. It is placed in a steel pipe with an outer diameter of 30 mm with an inner diameter of 2mm larger than this bar and an expansion coefficient aç = 125.107-1 °C, and is combined with a rigid plate from the top so that they move together. Find the stresses that will occur in steel and copper when the system is heated with a temperature difference of At = 80 °C. (EÇ = 200 GPa, EB = 100 GPa)

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.
