Unformatted text preview: Segment AC is 5 in long and has a diameter of 0.5 in, and segment CDB is 20 in long and has a diameter of 1 in. The shaft is fixed at ends A and B and subjected to a torque of 500 lbft at point D. Determine (a) the reaction torques at A and B, and (b) the maximum shear stress in the shaft. H.09: A composite shaft AB consists of a steel jacket (tube) fully bonded to a solid aluminum core. The jacket has a thickness of 1/16 in, and the core has a diameter of 2.5 in. Both the jacket and the core extend the full length of the shaft. A torque T is applied at B, and the shaft is fixed to the wall at A. The allowable shear stress is limited to 7 ksi in the steel and 3 ksi in the aluminum. Assume G is 11.2 × 10 6 psi for steel and 3.7 × 10 6 psi for aluminum. Find (a) the largest torque T which may be applied to the shaft, and (b) the corresponding angle of twist at B....
