Handle Spring
What is the real formula for a doorknob/handle.(using physic)?

I am trying to find the formula for a doorknob/handle. i know i need a angular spring equation and some kind of arc equation. Can you help me improve it or think of any other variables.

Torque = Force * Lever Arm * Sin of Angle Between Them
