Triangle Shaft Maximum Allowable Torsion

This calculator calculates the maximum allowable torsion for a shaft with a triangular shaped cross-section. This is done using the equation below.
﻿
T=τmaxb320T = \frac{\tau_{max}b^3}{20}T=20τmax​b3​
The following are the variables for the equations...
T = the torsion, twisting torque or tension. (Nm, lb f ft).
τ (max) = maximum shear stress (Pa).
b = the average side length of the triangle.
