I am trying to model a treybuchet arm. What I'm looking to achieve is an equation that shows the acceleration of the arm where the object is released. I have been looking into moments of inertia for the arm itself but I get stuck considering that there is a heavy weight used as Pot energy to get the arm to swing. Deriving a moment of inertia equation for a pole is easier with equally distributed math. For that do I need differential Equations? Any help with the mathematical setup is appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

If it is indeed differential equations does anyone know a good book or link that goes over using DEs in models. I have taken a class but you mostly just learn how to solve them, not how to set them up.

thanks
