A hollow aluminum shaft (see figure) has outside diameter d2 = 4.0 in. and inside diameter d1 = 2.0 in. When twisted by torques T, the shaft has an angle of twist per unit distance equal to 0.54°/ft. The shear modulus of elasticity of the aluminum is G = 4.0 ( 106 psi.
(a) Determine the maximum tensile stress (max in the shaft.
(b) Determine the magnitude of the applied torques T.
