Question: Determine the horizontal force P that must be applied perpendicular to the handle of the lever at A in order to develop a compressive force

Determine the horizontal force P that must be applied perpendicular to the handle of the lever at A in order to develop a compressive force of 12 kN on the material.Each single square-threaded screw has a mean diameter of 25 mm and a lead of 7.5 mm.The coefficient of static friction at all contacting surfaces of the wedges is μ_s = 0.2 and the coefficient of static friction at the screw is μ_s = 0.15.
