When quickly looking over your system definition, there seem to be multiple mistakes. For example `CP` does have a velocity in the inertial frame, namely `ux * N.x`. With `CP`...
 quick image which shows the problem you are working on, still have to put some extra things in it. At first thought you were doing a 3D problem, but...
Yeah fine, thanks for showing. Will have a lot more time this week, so will look into it somewhere in the coming days (probably tomorrow).
> Do you have any idea to resolve the `ImportError`? You should change the imports in [body.py](https://github.com/sympy/sympy/blob/37c7a4e7599ae60db3e12012097c175777db2254/sympy/physics/mechanics/body.py), specifically [this line](https://github.com/sympy/sympy/blob/37c7a4e7599ae60db3e12012097c175777db2254/sympy/physics/mechanics/body.py#L3) for: ```py from sympy.physics.mechanics.rigidbody import RigidBody from sympy.physics.mechanics.particle import Particle...
Do by the way also node that bodies can have loads stored internally, so you will also have to take those into account.
We indeed should add an example of how the combination works and is done. Probably easiest is to make a property `loads` as with the `JointsMethod` which returns a list...
I think this simplification is not done, due to the fact that `Derivative(theta, t)` is not per definition real and could have an imaginary part. Don't mind this comment, didn't...
@brocksam, @moorepants, @sidhu1012 FYI This PR should be merged after #24037
@brocksam Just updated the `set_vectors` method as we discussed and also added a test of how I would do the example we discussed.
Two required tests are failing, but I have no clue how I caused them and what they really mean.
