A pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminium alloy [E = 70 GPa] with a cross-sectional area of A1 = 2,400 mm2. Bar (2) is a bronze alloy [E = 100 GPa] with a cross-sectional area of A2 = 6,000 mm2. All bars are unstressed before the load P is applied; however, there is a 3-mm clearance in the pin connection at A. If a load of P = 795 kN is applied at B, determine the normal force in bar (1).
