Hello SymPy community,
As I had mailed a few days ago that I have started to draft a proposal to
improve and expand the control module in SymPy . You can go through this
discussion for the ideas (
https://groups.google.com/u/1/g/sympy/c/WpODTnY7Fh8 ).
I have completed it upto a good extent, so I
Dear Jason,
I would request you and other mentors / maintainers of the physics module
to have a look into it . I would be glad to have your reviews and
suggestions.
Thanking You,
Anurag Bhat .

Anurag,
My general advice is to fix what is there, make it robust (by demonstrating
on a large set of example problems), and document it extensively instead of
adding new features. To gain users, it is better to have a small number of
features that work really well over a larger number of features
Hi,
Looking for some help if possible. I was recently trying to get the
equations of motion of a double pendulum via SymPy. When I used
"kanes_equations" to obtain Fr and Fr* I got the above TypeError message.
I have the loads and the bodies contained in lists which are input into the
kanes_e
I have done all sorts of pendulae, single, double, triple.
If you could send your code, maybe I could find a mistake.

Thanks very much Peter.
I hope I'm not making an error but would welcome you finding one if I am.
I'm getting the same error in tutorial examples so suspect it's an error
with a new version of sympy or python, or something specific to my setup.
I'm using python 3.8 and sympy 1.8. I get the
Your loads were incorrect:
Try this:
loads = [ (p1, F_grav_1), (p2, F_grav_2) ]
When I changed this in your program, it worked, or at least there was no
error.
You have to give the points where the forces ‚attack‘, as tuples.
Otherwise, hwo would sympy.physics.mechanics ‚know‘, where the forces
In addition, you probably have a typo in this:
P1.set_ang_vel(A, omega1 * A.z)
P2.set_ang_vel(P1, omega*1* * P1.z)
It should probably be
P2.set_ang_vel(P1, omega*2* * P1.z)
With this change, it would calculate some rhs, like:
rhs = kanes.rhs()

Thanks very much Peter - that worked

Sorry for the typo, the equation is -B(t)^2 + B'(t) +1 =0. And the picture
is the right. The problem still remians.
