About the Torque Calculator
Torque is the turning effect of a force. Calculate torque, force or lever arm length.
How to use the Torque Calculator
- Enter two of Force (F), Lever Arm (r) and Torque (Ο), plus the Angle ΞΈ between the force and the lever.
- Press the matching Find button or Calculate.
Formula and method
Ο = r Γ F Γ sin ΞΈ. At 90Β° the force is most effective.
Worked example
A 50 N force applied 0.5 m from the pivot at 90Β° gives 25 NΒ·m of torque.
Tips
- A longer wrench gives more torque for the same force.
- Torque is measured in newton-metres (NΒ·m).
Frequently Asked Questions
They share units dimensionally, but torque is a turning effect (a vector) whereas work is energy transferred.
