Chapter 8.4, Problem 79P
If a horizontal force of P = 100 N is applied perpendicular to the handle of the lever at A, determine the compressive force F exerted 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, μs = 0.2, and the coefficient of static friction at the screw is, μs = 0.15.
