Question

Rigid bar ABCD is supported by a pin connection at A and by two axial bars (1) and (2). Bar (1) is a 24-in.-long bronze [E = 16100 ksi] bar with a cross-sectional area of 1.18 in.2. Bar (2) is a 40-in.-long aluminum alloy [E = 9400 ksi] bar with a cross-sectional area of 2.03 in.2. Assume L1=24 in., L2=40 in., a=31 in., b=41 in., and c=12 in. Both bars are unstressed before the load P is applied. If a concentrated load of P = 36 kips is applied to the rigid bar at D, determine:
(a) the normal stresses σ1σ1, σ2σ2 in bars (1) and (2).
(b) the downward deflection vD of point D on the rigid bar.
