A rigid body in equilibrium means that it is neither ... you can find the net torque about any point. Now for a force diagram. Yes. I got out of control on that diagram. OUT OF CONTROL.

Here is a diagram. It's a cool ... same as standing on a tightrope. The forces at the point of contact have to add up to the zero vector if it's in equilibrium. Rope Physics Let's take a closer ...
