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.

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.
(11) Find the power required to drive a power screw lifting a load of 40001b. A 2½-in double square thread with 2TPI. is to be used. The frictional radius of the collar is 2-in and the coefficients of friction are 0.l for the threads and 0.15 for the collar. The velocity of the nut is 10fpm .
A single trapezoidal metric thread power screw is to raise a load of 60 kN. The screw has a mean diameter of 34 mm and a pitch of 5 mm. The coefficient of thread friction and collar friction are 0.15 and 0.11, respectively. The collar mean diameter is 90 mm and the screw turns at 150 rpm. Determine the total torque required to raise the load in N-m.
