F360 can model (I think) every other sort of simple machine but so far as I can tell there isn't yet an ability to design systems like a block-and-tackle, syncromesh, or timing belts.
I'm not sure how you would handle tension or I'd imagine that in the simplest case it shouldn't be too hard to find the ideal case where the system is essentially under infinite tension subject to fixed boundary conditions (though solving for real / finite tension subject to gravity and boundary conditions shouldn't be terribly hard to do in near-real-time).
