Solve Prob. 2.117, assuming that the temperature of the rod is raised to 150°C and then returned to 25°C

Prob. 2.117

The steel rod ABC is attached to rigid supports and is unstressed at a temperature of 25°C. The steel is assumed elastoplastic with E = 200 GPa and σY = 250 MPa. The temperature of both portions of the rod is then raised to 1508C. Knowing that α = 11.7 X 102-6 /°C, determine

(a) the stress in both portions of the rod,

(b) the deflection of point C.
