What is the formula of torque?

\[ \tau = \mathbf{r} \times \mathbf{F} \]

In scalar form, the magnitude of the torque is:

\[ \tau = r F \sin(\theta) \]

where:

- \(\tau\) is the torque.

- \(r\) is the magnitude of the position vector, which is the distance from the pivot point to the point where the force is applied.

- \(F\) is the magnitude of the force.

- \(\theta\) is the angle between the position vector and the force vector.

The direction of the torque vector is perpendicular to the plane formed by \(\mathbf{r}\) and \(\mathbf{F}\), following the right-hand rule.
