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 = 0.2, and the coefficient of static friction at the
screw is μ's = 0.15.
Express your answer to three significant figures and include the appropriate units.
