To derive the force required to lift a load using a screw jack, we model the screw thread as an inclined plane. Let $P_L$ be the axial load (weight) to be lifted, and $P_R$ be the horizontal force applied at the mean radius of the screw to lift the load. Let $\alpha$ be the lead angle (helix angle) of the screw, and $\mu$ be the coefficient of friction between the screw and the nut. We define the friction angle $\lambda$ such that $\mu = \tan \lambda$.
We consider the forces acting on a block on an inclined plane, representing a segment of the screw thread.
$P_R$: Horizontal force applied to lift the load.
$P_L$: Vertical load acting
