The screw (double threaded, diameter of 10 mm, pitch of 2 mm) is turned to push the 400 kg block, which in turn pushes on a wedge of negligible mass. The wedge is used to lift the 200-kg block. If the coefficient of friction between all contacting surfaces is 0.2, what is the minimum torque that must be applied to the screw? Double-threaded screw: Diameter = 10 mm Pitch = 2 mm Wedge angle: 7° 400 kg 200 kg
