Thanks for the reply, but I'm really more interested in the resulting forces than just a stable/not stable decision. For instance, a stair-like stack of three boxes might have the direct weights of each of the boxes between their contact points but might still be unstable because of indirect...

Yes, it is possible. There are a number of ways to do this, but it all comes down to a rim attached to either the inside of the hole or the outside of the wheel. This rim slides through the supporting structure. Some practical examples, demonstrated on bicycle wheels...

Hi everyone! (little background: I'm trying to develop a small, quick 'n dirty static physics engine to determine whether a stacking of boxes is stable). If I have a 3D box (with the bottom in the horizontal plane), resting on n points (at [xn, yn]), and we apply a downward force F at [xF...
