Q.1 A solid circular shaft transmits a power of 100 kW at 1500 rpm. For a limiting shear stress of 70 MPa, find the diameter of the shaft. The solid shaft is replaced by a hollow shaft with inside diameter being equal to 0.75 times the outside diameter. What percent of saving in weight can be achieved by the replacement, if both shafts are of equal length, made of the same material, being subjected to equal maximum shear stress, and are transmitting equal powers at same speed?
