Thanks Jason. Those links helped. I guess if the module is not intended for simpler problems then that makes sense. I would say though that the documentation could benefit from more of a tutorial somewhere. I'll try to use it for a real problem at some point and then see what I think... --

Oscar, Also a specific answer to: > Suppose that I want to think about a simple 2D problem with a disc rolling down a surface inclined at angle beta with (Coulomb) friction coefficient mu. I want to know when/whether the disc will stick or slip and get the equations of motion for each case. How

Oscar, There are some rolling disc examples here: https://github.com/pydy/pydy/tree/master/examples Note that the PyDy project started as an independent thing build on top of SymPy, then the symbolics were merged into sympy as the mechanic module and the numerics are now in the standalone PyDy

[sympy] Using the mechanics API

2019-05-13 Thread Oscar Benjamin
Hi all, I haven't really looked much at SymPy's mechanics module even though mechanics is very much one of my interests and something that I like to think I know a bit about. Today I finally took a look at it and I found the whole API surprisingly complicated. I teach mechanics to undergraduate
