How to use shaft torque calculator
- Check the input units and assumptions.
- Review the result and example.
IN PRACTICE
Example
1000 N × 100 mm = 100 N·m; solid Ø30 mm: τ ≈ 18.86 MPa.
GOOD TO KNOW
Which model does this calculator use?
Pure static torsion in a solid circular shaft. No bending, axial load, keyways, fatigue, stress concentration or allowable material stress. Not a shaft selection or safety factor check.
