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, yF], how can I calculate the resulting forces Fn at these n points?
If the system is in equilibrium then [tex]\Sigma[/tex]Fn = F.
However, I must also consider that the system might not be in equilibrium (for instance, if all xn < xF), so I can't use equilibrium equations. I'd still like to know the forces in that case, though, so that I can calculate the resulting torque.
Is there an easy formula for this?
