from sympy import *
from sympy.physics.continuum_mechanics.beam import Beam
E, I = symbols('E, I')
b = Beam(9, E, I)
b.apply_load(-12, 9, -1)
b.apply_load(-50, 5, -2)
b.apply_load(-8, 0, 0, end=5)
b.apply_support(0, type='fixed')
b.apply_support(4.5, type='roller')
b.load

I suppose you are referring to R4.5000. This is a way to extract the
forces/moments from the above equation:
fs = list(b.load.free_symbols)
R45, R0, M0 = fs[1:]
M0, R0, R45
Now you can create a substitution dictionary and compute the load at a
given location.

had to rush through my project so i jerry rigged this piece of code i know
its not the most elegant way but yeah, it works.
b.applied_loads #gives all the loads applied to the beam as a
list of tuples and extracted all the unknow reaction forces and appending
them to a list
named r
free_symbols is a set. You shouldn't assume it will come out in any
particular order. The order for the exact same code might not even be
the same across different Python sessions.
