The clamp provides pressure from several directions on the edges of the board. If the square-threaded screw has a lead of 3 mm, mean radius of 10 mm, and the coefficient of static friction is µs = 0.4,determine the horizontal force developed on the board at A and the vertical forces developed at B and C if a torque of M = 1.5 N.m is applied to the handle to tighten it further. The blocks at B and C are pin connected to the board
