hi
let me says you have an arbitrary rigid body and a force F acts on this body at some point A, which is not the center of mass that is called C.
how do you get the equation of motion?
my idea was to separate out translation and rotation:
maybe the whole body moves by F=ma
and the rotation is given by: D=r x F where r is the distance between A and C.
but i am not sure at all about this.
by the way: i am rather looking for a general idea that would give me the equation of motion.
