Question

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 = 93 GPa] with a cross-sectional area of A_1 = 270 mm2. Bar (2) is an aluminum alloy [E = 71 GPa] with a cross-sectional area of A_2 = 730 mm2. All bars are unstressed before the load P is applied; however, there is a 4-mm clearance in the pin connection at A. If a load of P = 175 kN is applied at B, determine the normal stresses in both bars (1) and (2). the downward deflection of point A on the rigid bar.
