Q1- Find the power required to drive a 1.5-in power screw having double square threads with a pitch of 1/4 in. The nut is to move at a velocity of 2 in/s and move a load of F = 2.2 kips. The frictional coefficients are 0.10 for the threads and 0.15 for the collar. The frictional diameter of the collar is 2.25 in.
