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.

Instead of using the system shown in Figure.a to raise the mass m2, an engineer proposes to use two simple machines, the pulley and the inclined plane, to reduce the weight required to lift m2. The proposed design is shown in Figure.b. The pulley inertias are negligible. The available horizontal space limits the angle of the inclined plane to no less than 30°. Suppose that the friction between the plane and the mass m2 is negligible. Identify the equation to determine the smallest value m1 that can lift m2. (The answer should be a function of m2 and θ.)
