Spring actioned piston

  1. Jun 20, 2012 #1
    hi guys, this is my first post (and i am dont know much physics), i have a problem that i've ilustrated in a drawing that i attach to this post. Ok so it goes something like this ... if the spring is compressed manually , when i release it how do i calculate the torque of the wheel?
    this is the link to the drawing :

    Two equations will be most useful to you. One will be simple Hook's law for the spring. The other you can derive from a simple free body diagram, to show how force at the spring converts to torque to the wheel as a function of angular displacement of the wheel.
