MathLiveTorque
Torque measures the tendency of a force to rotate an object, computed as the cross product of the position vector from a reference point (such as a pivot) to the point of force application and the applied force. Its component along a rotation axis gives the torque about that axis. It is used throughout rotational dynamics and statics.
\tau = \mathbf{r} \times \mathbf{F}What the symbols mean
| torque vector (N·m) | |
| position vector from the reference point (e.g. a pivot on the rotation axis) to the point of force application (m) | |
| applied force vector (N) |
