A tubular aluminum alloy [G= 4,000 ksi] shaft is being designed to transmit 480 hp at 2,700 rpm. The maximum shear stress in the shaft must not exceed 6 ksi, and the angle of twist is not to exceed 4° in an 6-ft length. Determine the minimum permissible outside diameter if the inside diameter is to be 5/6 of the outside diameter. Answer: Dmin = i in.
