**Problem 8-82:**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 \( \mu_s = 0.2 \), and the coefficient of static friction at the screw is \( \mu'_s = 0.15 \).**Diagram Explanation:**The diagram illustrates a mechanical setup where a handle at point \( A \) is connected to a lever system. The handle is positioned 250 mm from the axis of rotation. Below the lever, there are two symmetrical wedges labeled \( B \) and \( C \), each angled at \( 15^\circ \).The setup is designed to adjust or compress the material at the center when a force is applied through the lever system. The interaction between the lever and the wedges involves friction, which has been taken into account with specified coefficients of static friction for both the wedges and the screw. This problem requires understanding forces and moments in mechanical systems, as well as the effects of friction.
