I would like to know where is the force that prevent the system to turn around. I use balls which are attrack with springs, the force of the spring is like 1/d or 1/d² like gravity for example. I see the force FR in the system, like the circle can only put a force in the center C I don't see the force which cancel the force FR, have you an idea ?
