Find the diameter of a solid steel shaft to transmit 30 kW at 400 r.p.m. The ultimate shear stress for the steel may be taken as 460 MPa and a factor of safety as 8. If a hollow shaft is to be used in place of the solid shaft, find the inside and outside diameter when the ratio of inside to outside diameters is 0.5
