Take the tour ×  I want to simulate and test set of 2D designs
that basically have pulley/gear/chain-linked systems under
Gravity (For e.g. to check how a pulley would rotate given
particular weights, of course I'm not talking about such small
systems, but systems where different pulleys/gears/weights are
linked together).  [Frictional/mechanical properties can be
neglected for my purposes]  Can anyone recommend any softwares
(Opensource/paid) that can be used to easily design pulleys,
gears, some chains(for e.g. to link a pulley to a gear) and
simulate their behavior when the system is placed in a
gravitational field?  I can construct the physical replicas of
the designs and test them but it's rather cumbersome and a waste
of resources to do so. Your help is much appreciated.

the mathematicians (if any other site) have an idea. They are
interested in such mathematical physics topics too and probably
know software to calculate stuff. –  Dilaton
