Find the diameter of a solid steel shaft to transmit 30 kW at 500 r.p.m. The allowable shear stress for the steel may be taken as 45 MPa . 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.
A body having a mass of 46 kg rests on a horizontal planse for which the coefficiant of friction f = 0.4. A force P acts ofn the body at an angle of 20 degrees with the horizontal. Find its magnitude for impending motion.
