Three bars, AB, AC, and AD, are pinned together to support a load P = 20 kN as shown in Fig. P-256. Horizontal movement is prevented at joint A by the short horizontal strut AE. Determine the stress in each bar and the force in the strut AE. For the steel bar, A = 200 mm and E=200 GPa. For each aluminum bar, A=400 mm^2 and E= 70 GPa.
