7. The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and C are stress-free. The load P is then applied and there is a temperature change in the steel rods. P = 35 kips with the stresses in the two steel rods equal. Assume that there is no buckling in the rods. The coefficient of linear expansion is 6.5 x 10^-6 per degree F and E = 29 x 10^6 psi for steel.
