Torque Calculator

Enter a force, lever arm length, and angle to calculate the resulting torque.

15.000 N·m

Uses τ = Fr sin(θ) — torque is maximized when the force is applied perpendicular to the lever arm (θ = 90°) and zero when applied along the arm (θ = 0°).

How to use this tool

  1. 1Enter the applied force in newtons.
  2. 2Enter the lever arm's length in meters.
  3. 3Enter the angle between the force and the lever arm.
  4. 4See the resulting torque.

Frequently asked questions

Why does angle matter?+

Torque depends on the perpendicular component of the force — it's maximized at 90° and drops to zero when the force is applied directly along the lever arm (0°).
