Here is an example I worked on getting the contact forces for a bicycle tires using the aux equations:
https://github.com/moorepants/pydy/blob/bicycle-tire-constraint-forces/examples/bicycle_wheel_contact_constraint_forces/whipple.py Here is a manual method of doing aux equations too: https://nbviewer.jupyter.org/github/moorepants/mae223/blob/master/content/lecture-notebooks/mae223-l19-01.ipynb, KanesMethod should make the same result.
