Design the outside and inside diameters for a hollow stell shaft subjected to a torque of 1,000,000 in-lb. The maximum shear stress developed in the shaft is not to exceed 8,000 psi. The inside diameter is to be 2/3 of the outside diameter. Calculate the angle of twist in degrees for a 14 foot length of this shaft.

2. A composite shaft is made of slipping a bronze tube of 3-in. outer diameter and 2-in. inner diameter over a solid steel shaft of the same length and 2-in. diameter. The two components are fastened rigidly together at their ends. What is the largest torque that can be carried by the composite shaft if the working shear stresses are 10 ksi for bronze and 14 ksi for the steel? If the hollow tube is made out of steel and the solid shaft is made out of bronze, what is the largest torque that can be carried by the composite shaft if the same working shear stresses are applied? For bronze, G = 6 x 10° psi, and for steel, G = 12 x 10°.
