1. (40 points) A single 3 inch major diameter, single-threaded screw with modified square threads is used to raise and lower a 30 ton gate. One ton = 2000 lbs. The screw has a friction coefficient of 0.15. We can assume that there is no collar friction. Find the power required to drive the screw when the gate is raised at 5 feet/minute.
