## Main Question or Discussion Point

Yes, I understand the equation for the cross product and the right hand rule.

People keep using this example with a wrench twisting a bolt and the right hand rule makes sense there. Okay fine, the force is perpendicular in that case...

The bolt won't experience a perpendicular force anymore because it lacks grooves, no matter how much you turn. I.E. the bolt is completely smooth on the inside, where it contacts the nut.

I think that's part of what I'm misunderstanding here. Is there some inherent perpendicular force that's part of torque?

Let me know if I'm not explaining my confusion clearly.
