Shaft shear stress when horsepower, speed and shaft diameter are knownToggle
- This calculator can be used to determine a shaft's shear stress (Ss) knowing the horsepower (HP), shaft diameter (D), and rotation speed (N). If you enter any three of these variables as inputs, the calculator will determine the fourth variable.
- The shaft is experiencing pure torque.
- There are no stress risers in the shaft.
- Multiply your result by the stress riser value to get your actual shaft shear stress.
