Problem 2 (25 Marks) A single square-thread power screw has an input power of 3 kW at a speed of 1 revis. The screw has a diameter of 40 mm and a pitch of 8 mm. The frictional coefficients are 0.14 for the threads and 0.09 for the collar, with a collar friction radius of 50 mm. Find the axial resisting load F and the combined efficiency of the screw and collar.
