    Frictionless Axis of rotation

    I want to analyse the force required to compress a spring, the lever has a 'frictionless' pin at the bottom, to rotate around and the spring at the top. When I analyse the lever bends around the axis(assumes 100% friction) - how can I get it to rotate around the pin freely? thanks
