1. The problem statement, all variables and given/known data I have a situation a shown in the diagram below. A lever with a gas compression spring opposing it's turning. I want to find the force acting on the spring, F1, for a given inital force @ F0. [PLAIN]http://img18.imageshack.us/img18/9830/lever01.png [Broken] 2. Relevant equations 3. The attempt at a solution I don't think this is a trivial lever problem but I may be wrong???
