A 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) http://staff.fit.ac.cy/eng.la/AMEM316/MDESIGN%20Power%20Screw.pdf bruno stairway chair lifts
