Determine the force required to release the clamp in the previous problem. Assume again that the force acts 3.5 in from the centerline of the screw. Assume that the equation for the torque to lower a load using a screw with square threads is derived in the same manner as the torque to raise a load using a screw with square threads. Express your answer symbolically in terms of the axial load on the screw (i. e. P
