If the clamping force on the boards is 600 lb, determine the required magnitude of the couple force 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 1 in, and a lead of 0.25 in. The coefficient of static friction is, μs = 0.3.
