Torque Calculator
Calculate torque from force, lever-arm distance, and the angle between the force and the lever arm.
Enter torque details
Result
Enter the force, lever-arm distance, and angle, then calculate the torque.
What torque means
Torque is the turning effect of a force around a pivot or axis. More force or a longer lever arm usually creates more torque.
Why the angle matters
Only the component of force perpendicular to the lever arm creates rotation. The sine of the angle accounts for this effect.
Common torque uses
Torque calculations are used for engines, bolts, shafts, levers, hinges, rotating machinery, and structural systems.
Frequently asked questions
What formula does this calculator use?
Torque is calculated using τ = rFsin(θ), where r is lever-arm distance, F is force, and θ is the angle between them.
What is the SI unit of torque?
The SI unit of torque is the newton-metre, written N·m.
When is torque at its maximum?
Torque is maximum when the force acts at 90° to the lever arm because sin(90°) equals 1.
Can torque be zero even when force is applied?
Yes. Torque is zero when the force acts directly along the lever arm because the perpendicular force component is zero.
