General formula for torsion section modulus
General formula for torsion section modulus
(OP)
Hello,
Is there one single formula which can give the torsional section modulus for all shapes (either solid or hollow)? I want to write a script for the same.
Dividing the polar moment of inertia with the extreme fiber doesn't give the right results for all shapes.

Su

where b= length of each cross-sectional element & t= thickness of each cross-sectional element
For closed sections, there are various formulas.
