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 = 94 GPa] with a cross-sectional area of A₁ = 350 mm². Bar (2) is an aluminum alloy [E = 69 GPa] with a cross-sectional area of A2 = 590 mm². Assume L₁= 2220 mm, a = 1100 mm, b = 640 mm, c = 480 mm, and L₂=1710 mm. If a load of P = 26 KN is applied at B, determine (a) the normal stresses (positive if in tension and negative if in compression) in both bars (1) and (2). (b) the downward deflection of point A on the rigid bar. LA (1) a C b D L2
