A steel [E = 30,700 ksi, α = 6.9×10–6/°F] bar is held between two rigid supports. The bar is stress free at a temperature of 62°F. The bar is then heated uniformly. If the yield strength of the steel is 48 ksi, determine the temperature at which yield first occurs.

Rigid bar ABC is supported by pin-connected axial member (1) and by a pin connection at C as shown. A 6,300-lb concentrated load is applied to the rigid bar at A.
