The composite shaft shown in the figure consists of an aluminum alloy tube (1) securely bonded to an inner brass core (2). The aluminum sleeve has an outside diameter of 58 mm, an inside diameter of 47 mm, and a shear modulus of G? = 26 GPa. The solid brass core has a diameter of 47 mm and a shear modulus of G? = 44 GPa. The length of the assembly is L= 590 mm If the composite shaft is subjected to a torque of T = 3.0 kN-m determine: (a) the maximum shear stresses in the aluminum tube and the brass core. (b) the rotation angle of end B relative to end A. (1) 1? = (b) -A= i L B T MPa MPa rad
