The C clamp shown in the figure for Prob. 8–7 uses a 5/8 in-6 Acme thread. The frictional coefficients are 0.15 for the threads and for the collar. The collar, which in this case is the anvil striker’s swivel joint, has a friction diameter of 7/16 in. Calculations are to be based on a maximum force of 6 lbf applied to the handle at a radius of 2 ¾ in from the screw centerline. Find the clamping force.
