A 24-in-long copper bar with a yield strength of 30000 psi


A 24-in.-long copper bar with a yield strength of 30,000 psi is heated to 120°C and immediately fastened securely to a rigid framework. The coefficient of thermal expansion for copper is 16.6x10-6 (1/oC).

a) Will the copper deform plastically during cooling to 25°C?

b) How much will the bar deform if it is released from the framework after cooling?
