Determine the couple forces F that must be applied to the handle of the machinist?s vise in order to create a compressive force FA in the block Neglect friction at the bearing A. The guide at B is smooth so that the axial force on the screw is FA. The single square-threaded screw has a mean radius b and a lead c, and the coefficient of static friction is ?s.
a = 125 mm
FA = 400 N
b = 6 mm
c = 8 mm
? s = 0.27
