When trying to solve the following system with an indeterminacy of 1 an error is issued when calculating the beams `deflection()`. However, all other quantities (`reaction_loads`, `shear_force`, `bend…

This is a discussion prior to starting the implementation of a class `Truss`, which helps in solving for the reactions in a loaded Truss.
This is the API that I had initially thought of :

As we plan to implement column buckling calculations in the continuum mechanics module, here is what I have thought of regarding the API and its implementations:
The API can be seen from the stage -I…

I see a lot of deprecation warnings when running the doctests. These are warnings coming from within sympy when running its own doctests. These need to be fixed before sympy 1.13 can be released.

The `sympy.physics.continuum_mechanics.beam` uses the `SingularityFunction` to create symbolic expression for the loads. The plotting module converts the symbolic expression to a lambda function to be…

I have the following snippet
```python
from sympy import symbols, sqrt, integrate
a, b, r = symbols("a b r")
fun = sqrt(1 - r**2)*(a*r**3 + b*r**4)
integrate(fun, (r, 0, 1))

### Improving the quality of the plots
It would be great if we could see a few special points like (discontinuous, non-differentiable, maximum and minimum) points being pinned in the plots.
Somet…
