WebA screw jack is a mechanical device that can increase the magnitude of an effort force. The effort force for a screw jack when neglecting friction can be expressed as F = (Q p) / (2 π R) (1) where F = effort force at the end of the arm or handle (lb, N) Q = weight or load (lb, N) p = pitch - distance or lead of thread in one turn (in, m) WebScrew Thread Design Screw Thread Fundamentals A screw thread is defined as a ridge of uniform section in the form of a helix on either the external ... To determine the force required to strip the threads, multiply the shear strength by the cross sectional area being sheared. The difficulty lies in determining the
