About this calculator

How it works

Torque is the turning effect of a force about an axis. Maximum torque occurs when force is perpendicular to the moment arm.

Formulas

Formulas used

Torque

T = F r sin(theta)

Worked example

Example calculation

Torque

150 N at 0.25 m and 90 deg gives T = 37.5 N.m

Reference

What the results mean

Torque

Rotational moment about an axis.

Moment arm

Perpendicular distance from axis to force line of action.

Assumptions and limits

Before using the result

Calculations are simplified engineering estimates for idealized geometry and operating conditions.
Real systems may require efficiency, fatigue, slip, vibration, lubrication, thermal, tolerance, and manufacturer data checks.
Use applicable standards, safety factors, test data, and qualified engineering judgement for final machine design.

FAQ

Torque Calculator questions

Can I use different units?

Yes. Select the unit beside each input. The calculator converts values internally before solving.

Are these results suitable for final machine design?

Use the results for education, screening, and early design checks. Final designs should include verified data, safety factors, standards, fatigue, tolerances, and manufacturer guidance.

Why can real mechanical systems differ from the result?

Real systems include friction, slip, wear, vibration, misalignment, efficiency losses, and manufacturing variation.
