Question
The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and C are stress-free at 0 °F. 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 = 29x10^6 psi and x = 6.5 x 10^-6/ op for steel.
