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 d₁ = 1.0 in. External torques are applied to the rod at point B and point C. Let L₁ = 53.0 in, LB = 42.0 in, dA dд = 3.0 in, dB = 2.2 in, TB = 9.0 kip in, and Tc = 10.0 kip in . • . B di TB Tc LA LB Part A- Angle of twist at point B Determine the angle of twist, dg, experienced by the rod at point B.
