Shaft Torque / Torsional Stress Calculator
Estimate maximum elastic shear stress in solid and hollow circular shafts.
Torque and section
Torsional section result
Maximum shear stress94.314 MPa
Solid circular shaft
- Polar moment J
- 79,521.6 mm⁴
- Maximum shear stress
- 94.314 MPa
- Factor of safety
- 2.651
This elastic calculation assumes a uniform circular shaft under pure torque. Stress concentrations, fatigue, keyways, combined loading and material yield criteria require separate checks.
