Algodoo

this demonstrates how to fix belts that freak out. (take a look on the right quick when you start)
Xray pointed out my mistake, this properly demonstrates how this should be done.
allow me to explain~~ the one on the left has the hinges set to autobend: on while the other does not. this demostrates how the hinges react when carring a load. you can see that the one on the left carrys a lot more than the one on the right (which struggles to carry it's own load.....)

My mistake:
Instead of comparing between the two obvious differences i decided to use the chains given by algodoo, however theirs had autobend to true. I hadn't noticed because the preformance of the left was still better none the lease. allthough now i have fixed my mistake.
