The light rigid bar ABCD shown in Fig. P-252 is pinned at

The light rigid bar ABCD shown in Fig. P-252 is pinned at B and connected to two vertical rods. Assuming that the bar was initially horizontal and the rods stress-free, determine the stress in each rod after the load after the load P = 20 kips is applied. A 4 ft Aluminum L = 4 ft A = 0.75 in E = 10 x 105 psi B Steel L = 3 ft A = 0.5 in E = 29 x 10 psi D -2 ft2 ft. Figure P-252
