Two 400 mm diameter pulley are keyed to a simply supported shaft 500mm apart. Each pulley is 100 mm from its support and has horizontal belts, tension ratio being 2.5. If the shear stress is to be limited to 80MPa while transmitting 45 kW at 900 rpm. Find the shaft if it is to be used for the input - output belts being on the same or opposite sides.
