I have a child in fourth grade, and like many his age, he is a natural born
lawyer looking for loopholes, so 'm well versed in the tactic because it is
hard to resist....
If you notice my original post, I didn't even mention pulleys, I just asked
about two circles in 3D space. I was just trying to solve one part of the
stretched rubber band, not the entire rubber band... so there.... :^P
Once again you were ahead of me.
