Description:

KNOWN: A double thread Acme screw and a thrust collar, each with known diameter and running friction coefficient, are used to raise a specific load.
FIND: a) Determine the screw pitch, lead, thread depth, mean pitch diameter, and helix angle.
b) Estimate the starting torque for raising and lowering the load.
ASSUMPTIONS: 1) The starting and running friction remain steady.
2) Starting friction is about one-third higher than running friction.
