PROBLEM No. 2 The rigid bar ABCD of negligible weight is initially horizontal, and the steel rods attached at A and Care 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 = 29x10° psi for steel. (Provide FBD and movement diagram in your computation). A = 0.5 in.² 3 ft | A | 20 kips + 2 ft → 2 ft → 4 ft 4 ft -
