A uniform steel rod of cross-sectional area A is attached to rigid supports at both ends and is unstressed at a temperature of 8°C. The steel is assumed to be elastoplastic with yield stress = 250 MPa and E = 200 GPa. Knowing that a = 11.7 x 106/°C, determine the stress in the bar when the temperature is raised to 165°C and after the temperature has returned to 8°C.
