The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and C are stress-free. If the temperature is dropped to -40°F and the 20-kip load is then applied, determine the stress in each steel rod at A and C. Use E = 29x106 psi and x = 6.5 x 10-6n for steel. A = 0.5 in.2 3 ft | 20 kips 4 ft - 4 ft 2 ft 2 ft A = 0.75 in.
