    Analyzing applied torque to one of lug nuts instead of wheel center

    We all know that torque consists of force and distance. If we apply torque to the center of a car wheel, the force that the tire exerts to the ground can be calculated by dividing the torque by tire radius but what about applying torque to one of lug nuts which is off center? In the above...
