rotation collision response?
-
Hi all! when this impulse based equation can equal to zero: w'=w+(j/I)*r*n; n normal contact;j impulse;I inertia;

What is your question ? And I guess more details will be welcomed.

as you know: https://en.wikipedia.org/wiki/Collision_response[^] just that w will never be zero, and need always two points of contact to be;(the eqation above is elastic collision with rotation no friction)! __________ \/__________ a triangle can never stand like this!(in a real world or can it!?) see here(http://i.stack.imgur.com/o9P7V.png[^] what if the ball was heading the center of the bar, the bar won't spin right! but we know that a force in a direction in a center of mass mmake angular velocity zero right! but this equation from wiki never make it until there is two points of contact, is that is!?

Ok, the wording is not obvious for not English native people. A couple of sentences explaining what you are looking for will not arm.
