The figure shows a system with a block m1 attached to a simple square thread screw with a mean diameter of 10 mm, a pitch of 3 mm and whose coefficient of static friction on the thread is 0.35. Block m1 is attached to block m2 by a rope, each of blocks m1 and m2 have a mass of 4 kg.Block m2 is in turn attached to a 15-kg block W by another rope, which passes over a static drum where the coefficient of static friction is 0.20. Determine the required Moment M that must be applied to the screw to start lifting block W. The coefficient of static friction between the surface and blocks m1 and m2 is 0.25.
