Ellipse Shaft Torsion

This calculator calculates the allowable torsion for an ellipse-shaped shaft. This is done using the equation below.
﻿
T=π×τmaxb2h16T = \frac{\pi\times\tau_{max}b^2h}{16}T=16π×τmax​b2h​
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).
h = the height of the shaft.
b = the breadth (width) of the shaft.
