If the clamping force on the boards is 600 lb, determine the required magnitude of the couple forces that must be applied perpendicular to the lever AB of the clamp at A and B in order to loosen the screw. The single square threaded screw has a mean diameter of 2 in and a lead of 0.25 in. The coefficient of friction is 0.3.
