The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and C are stress-free. If a 20-kip load is applied, determine the vertical displacement in the bar at A and C that will cause a stress in the rod at C to be 50 ksi. Indicate the direction of movement. Use E = 29x106 psi for steel. A = 0.5 in.2 3 ft A B D 20 kips 2 ft2 ft- 4 ft 4 ft A =0.75 in.2
