Strength of Materials: Torsional Loading Non-Circular Cross-Sections

Non-Circular Cross-Sections

Torsional stress is much more difficult to calculate when the cross-section is not circular. Below I show how to calculate the torsional stress and angle of twist for an equilateral triangle, rectangle, square, and ellipse. However, there can be many more cases where you will have to derive these equations on your own.
