Find the diameter of a solid steel shaft to transmit 43kW at 5.25 rps. The ultimate shear stress for the steel may be taken as 410MPA and a factor of safety as 5. If a hollow shaft is to be used in place of the solid shaft, find the inside and outside diameter when the ratio of outside to inside diameters is 1.8.
