The pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminum alloy [E = 65GPa] with a cross-sectional area of A_{1} = 850m * m ^ 2 Bar (2) is a bronze alloy [E = 100GPa] with a cross-sectional area of A_{2} = 540m * m ^ 2 Assume L_{1} = 1.9m L_{2} = 2.2m , a = 0.5m b = 1.6n , and c = 1.3 m. All bars are unstressed before the load P is applied; however, there is a 1.6-mm clearance in the pin connection at A. If a load of P = 55 KN is applied at B, determine: (a) the normal stresses Oj, 62, in both bars (1) and (2). (b) the normal strains E1, E2, in bars (1) and (2). (c) determine the downward deflection VA of point A on the rigid bar
