Question: A 5 0 - in . - long copper bar with a yield strength of 3 0 , 0 0 0 psi is heated to

A 50-in.-long copper bar with a yield strength of 30,000 psi is heated to 114C and immediately fastened securely to a rigid framework. Will the copper deform plastically during cooling to 25C?(The modulus of elasticity of copper is 18.1106 psi.)
YesNo
How much will the bar deform if it is released from the framework after cooling? (Enter the change in length in inches.)
