Verification of sections to torsion

The spreadsheet reports many verifications of sections in torsion loading. The aim is to offer a design tool both for fast and detailed calculation for common practical mechanical sections.

A number of 15 investigated cases are reported.


The calculation is done considering the formulas in "Roark's Formulas for Stress and Strain" 7th Ed.
