How can a force be applied not to the center of a rigid body object, but to one specific vertex of the object?
Simulations which include moments of inertia (https://en.wikipedia.org/wiki/Moment_of_inertia) and off-center forces can be created by combining objects though rigid-constraints, and applying forces ...
