#codebase rewrite the entire script that i have open. keep all formatting and naming conventions such as they currently are. variablenames are always lowercase. keep the variablenames in the latex equation the same. if variable descriptions are given or found, copy precisely. LaTeX variables should be rounded to 3 decimals.  Import the necessary typehinting with type alias units found in type_alias.py and remove the unused imported type aliases. Forces in N, (Bending) moments in Nmm, distances in mm, areas in mm^2, Stress in MPa, angles in DEG, no unit is DIMENSIONLESS. when dealing with angles, use np.deg2rad. ":math:" sections should be fully latex based. Formula
