If the required clamping force at the board A is to be F, determine the torque M that must be applied to the handle of the hold-down clamp to tighten it down. The single square-threaded screw has a mean radius r and a lead r1, and the coefficient of static friction is µs.
Given:
F = 70 N
r = 8 mm
rl = 2 mm
µ s = 0.38
