The axial assembly consists of a solid 1.18-in.-diameter aluminum alloy [E = 11200 ksi, v = 0.2, a = 13.3 x 10-6/°F]rod (1) and a solid 1.48-in.-diameter bronze [E = 17200 ksi, v = 0.14, a = 7.2x 10-6/°F] rod (2). Assume L1=13 in., L2=26 in. If the supports at A and C are rigid and the assembly is stress free at 5°F, determine: (a) the normal stresses o1,02 in both rods at 161°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. (1) (2) L1 L2
