Torque = Force * distance of lever arm from the point of force to the axis of rotation

Friction = Coefficient of friction (represented by the greek letter mu) * normal force

Depending on whether the object is moving or stationary determines the coefficient you use...Static coefficient for stationary objects, kinetic for moving objects.
