Learning Goal: To determine the angle of twist on a composite rod given the geometry and externally applied torques, to properly apply a sign convention to determine the angle of twist, to use a torque diagram to aid in determining the angle of twist, and to determine the maximum applicable torque given a maximum allowable angle of twist. The rod shown below is made of two different materials. Segment AB is made of aluminum (G = 3.9 × 106 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 d; = 1.0 in. External torques are applied to the rod at point B and point C. Let LA = 59.0 in, LB = 43.0 in, d₁ = 3.6 in, A B dB = 2.4 in, TB = 9.0 kip in, and To = 13.0 kip in. LA dB di LB Tc
