Torque from force and lever arm
Calculate torque magnitude from a force, perpendicular lever arm, and angle between them.
Method and scope
τ = rF sin θ.
Use torque from force and lever arm for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Applied force — N, kN, lbf
- Distance from axis — m, cm, mm, in
- Angle between arm and force — rad, °
SOURCE AND LIMITS
Assumptions: The force acts at the entered distance from the rotation axis. The angle is between the lever-arm vector and force.
Limitations: The output is torque magnitude; axis direction and sign convention are omitted.
