The pin-connected structure consists of a rigid bar ABCD and two axial members. Bar (1) is bronze [E = 90 GPa] with a cross-sectional area of A1 = 510 mm². Bar (2) is an aluminum alloy [E = 68 GPa] with a cross-sectional area of A2 = 320 mm². A concentrated load of P - 75 kN acts on the structure at D. Assume L1-840 mm., L2-420 mm., a-650 mm., b-260 mm., and c-1070 mm. Determine: (a) the normal stresses o1,02 in both bars (1) and (2). (b) the downward deflection vp of point D on the rigid bar.
