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}

The following are the variables for the equations...

  1. T = the torsion, twisting torque or tension. (Nm, lb f ft).
  1. τ (max) = maximum shear stress (Pa).
  1. b = the average side length of the triangle.
