Pure ShearProblem 3.5-1A hollow aluminum shaft (see figure) has outside diameter d24.0 in. and inside diameter d12.0 in. When twisted by torques T, the shaft has an angle of twist per unitdistance equal to 0.54°/ft. The shear modulus of elasticity of thealuminum is G4.0 106psi. (a)Determine the maximum tensile stress maxin the shaft.(b)Determine the magnitude of the applied torques T.Solution 3.5-1Hollow aluminum shaftSECTION 3.5Pure Shear209Ld2d1d2TTd2d1TTd24.0 in.d12.0 in.0.54 /ftG4.0106psiMAXIMUM SHEAR STRESSmaxGr(from Eq. 3-7a)rd2/22.0 in.max(4.0
