The pin-connected structure shown in the figure consists of a rigid beam ABCD and two supporting bars. Bar (1) is a bronze alloy [E = 97 GPa] with a cross-sectional area of A₁ = 220 mm². Bar (2) is an aluminum alloy [E = 71 GPa] with a cross-sectional area of A2 = 550 mm². All bars are unstressed before the load P is applied; however, there is a 3-mm clearance in the pin connection at A. Assume L₁ = 1620 mm, a = 1120 mm, b = 680 mm, c = 500 mm, and L₂ = 1200 mm. If a load of P = 112 kN is applied at B, determine (a) the normal stresses in both bars (1) and (2). (b) the downward deflection of point A on the rigid bar. 4 (1) L a A b (2) D L2
