Design a hollow steel shaft to transmit a torque of 13,000 lb-in. The allowable shear stress in the shaft is 9000 psi. The outside diameter is to be twice the inside diameter. I'm not sure how to solve this problem, could you please walk through the process with me step-by-step? Thanks in advance. The answer is NOT 0.973 inches.
A single solid circular shaft 400 mm diameter running at 250 RPM, is to be replaced by two hollow circular shafts of equal size running at 150 RPM and developing 50% additional power. The internal diameter of hollow shaft may be taken as one third of their external diameters. If the working stress of the new shaft is 30% greater than that of the former, find the external and internal diameter of hollow shafts.

Please solve with clear explanation. Q.solid aluminium shaft 1 m long and 50 mm diameter is to be replaced by a tubular steel shaft of the same length and same outside diameter such that each of the two shafts could have the same angle of twist per unit torsional moment over the total length. What must be the inner diameter of the tubular shaft? Modulus of rigidity of steel is three times that of aluminium.
