Shaft shear stress when horsepower, speed and shaft diameter are known

Toggle
  1. This calculator determines your expected shear stress due to a pure torque in a uniform shaft with no stress risers.
  1. The shaft is experiencing pure torque.
  2. There are no stress risers in the shaft.
  3. Multiply your result by the stress riser value to get your actual shaft shear stress.
