The shaft in Figure P12-3 is part of a special machine designed to reclaim scrap aluminum cans. The gear at B delivers 5 hp to a chopper that cuts the cans into small pieces. The V-belt sheave at D delivers 3 hp to a blower that draws air through the chopper V-belt sheave E delivers 3 hp to a conveyor that raises the shredded aluminum to an elevated hopper The shaft rotates at 480 rpm. All power comes into the shaft through the chain sprocket at C. Use AISI 1137 OQT 1300 steel for the shaft. The elements at B, C, D. and E are held in position with retaining rings and keys in profile keyseats. The shaft is to be of uniform diameter, except at its ends, where the bearings are to be mounted. Determine the required diameter
