Question
The rod shown below is made of two different materials. Segment AB is made of
aluminum (G=3.9x106 psi). Segment BC is bonded to segment AB and is made of
brass (G=5.6×106 psi). Segment BC is hollow and has an inner diameter of di = 0.8 in.
External torques are applied to the rod at point B and point C. Let LA = 53.0 in, LB =
42.0 in, dA = 3.8 in, dB = 2.5 in, TB = 7.0 kip?in, and TC = 18.0 kip?in.
