>>>However, if the wall was hinged, like a door, punching the wall at any point other then the center of mass of the door would cause the wall to rotate, even though no torque is applied to the wall.<<<

JJA,

Even though no torque is applied to the wall?

What is the force that causes the wall to rotate?

Punching a hinged wall at any point other than center is not applying torque?

I'm confused with your statement. Can you clarify?


thanks,
