A solid steel shaft of 500 mm long between bearings 'A' and 'C' and carrying a cast iron pulley at 'B' which is 300 mm from bearing 'A'. The pulley is directly coupled to a 5 kW motor running at 750 rpm. The motor is located left side of the bearing 'A'. The cast iron pulley is 250 mm in diameter and weighs 100 N and is driving a machine shaft running below it. The belt from the pulley to the machine is inclined 60° to the vertical. Determine the appropriate diameter of the shaft, assuming moderate shock conditions, the friction factor between the pulley and the belt as 0.3, factor of safety 4.0.
