A pulley 500 mm diameter is driven at 375 rev/min by a belt 200 mm wide by 12 mm thick. The tension in the tight side of the belt is three times the tension in the slack side. Calculate the maximum power that can be transmitted if the stress in the belt is not to exceed 400 kN/m2, neglecting the stress set up in the belt due to centrifugal force.
