Question

Rigid bar ABCD is supported by a pin connection at A and by two axial bars (1) and (2). Bar (1) is a 28-in.-long bronze [E = 14500 ksi, α=α= 9.6 × 10⁻⁶/°F] bar with a cross-sectional area of 1.00 in.². Bar (2) is a 40-in.-long aluminum alloy [E = 9900 ksi, α=α= 11.7 × 10⁻⁶/°F] bar with a cross-sectional area of 2.25 in.². Both bars are unstressed before the load P is applied. Assume L₁=28 in., L₂=40 in., a=40 in., b=42 in., and c=10 in. If a concentrated load of P = 29 kips is applied to the rigid bar at D and the temperature is decreased by 80°F, determine:
(a) the normal stresses in bars (1) and (2).
(b) the normal strains in bars (1) and (2).
(c) the deflection of the rigid bar at point D.
