Rigid bar ABCD is supported by a pin connection at A and by two axial bars (1) and (2). Bar (1) is a 32-in.-long bronze [E = 13700 ksi] bar with a cross-sectional area of 1.29 in.2. Bar (2) is a 48-in.-long aluminum alloy [E = 10300 ksi] bar with a cross-sectional area of 2.19 in.2. Assume L1=32 in., L2=48 in., a=25 in., b=57 in., and c=15 in. Both bars are unstressed before the load P is applied. If a concentrated load of P = 26 kips is applied to the rigid bar at D, determine:(a) the normal stresses σ1, σ2 in bars (1) and (2).(b) the downward deflection vD of point D on the rigid bar.
The axial assembly consists of a solid 1.01-in-diameter aluminum alloy [E = 8900 ksi, v = 0.33,a = 12.4x 10-6/°F] rod (1) and a solid 1.63-in-diameter bronze [E = 15400 ksi, v= 0.17, a = 7.3x 10-6/°F] rod (2). Assume L,=15 in., L2=29 in. If the supports at A and Care rigid and the assembly is stress free at 6°F, determine: (a) the normal stresses o1,02 in both rods at 167°F (positive if tensile, negative if compressive). (b) the displacement ug of flange B (positive if to the right, negative to the left). (c) the change in diameter Ad, of the aluminum rod. B (1) L1 L2 Answers: (a) o = ksi, o2 = ksi (b) ug = in.
