Sort of, and that actually might work too. Let me try and explain it - start with this graphic:
The line = a stick, attached where it meets each box
Scenario #1: if you slid box A to the right, box B would follow accordingly with it. If you slid box A left, box B wouldn't move with it until you got far enough left and the stick would pivot till it couldn't an more
Scenario #2: The same as #1, but depending on how fast you slide box A, box B would continue to move via centrifical force (I'm guessing this is harder to replicate, but I could be wrong)
Make sense now?
Thanks everyone for the replys. I appreciate the help.
