Traction After a skiing accident, your leg is in a cost and supported in a traction device, as shown in Figure. Find the magnitude of the force exerted by the leg on the small pulley. (By Newton’s third law, the small pulley exerts an equal and opposite force on the leg.) Let the mass m be 2.50 kg.
