Establishing equations for a worm screw mechanism

  1. Aug 25, 2016 #1
    Hey guys :)

    So I'm looking to form equations that I can apply a Laplace transformation to. The mechanism specifically is a trailer jack - it converts rotational motion to linear motion. And its high torque provides a mechanical advantage to lifting heaving loads.

    Can anyone help me form differential equations that I can apply a Laplace function to?

    What is the actual arrangement of components you want to analyse ? Picture or good drawing please .

    Why do you think the motion of a jack needs to be described with a differential equation?
    The motion can be described with a simple linear equation; x rotational motion equals y change in height.
