Find torque τ = r F sinθ, the turning effect of a force about a pivot.
| Torque (N·m) | – |
Use this calculator for the magnitude of torque: τ = r F sinθ. r is the distance from the pivot to the point of application; θ is the angle between r and F.
At 90° sinθ = 1 and torque is maximum. SI unit is N·m. For converting N·m to lbf·ft, use the torque converter. This is a single force, not a full statics problem with several moments.
Lever arm (m): Pivot to the force, in metres.
Force (N): Force in newtons.
Angle (°): Angle between the arm and the force. 90° is perpendicular.
Torque (N·m): τ = r F sinθ.
