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}

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. h = the height of the shaft.
  2. b = the breadth (width) of the shaft.
