The sign of the torque is found using the right hand rule. The net torque can be found from summing the individual torques about a given axis.

Then only the component of the force \(F\) perpendicular to the moment arm contributes to the torque: The direction of \(\boldsymbol{\tau}\) is given by a right-hand rule: if you curl the fingers of your right hand from \(\mathbf{r}\) into \(\mathbf{F}\), then the thumb of your right hand points in the direction of \(\boldsymbol{\tau}\).

A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it. To understand what factors affect rotation, let us think about what happens when you open an ordinary door by rotating it on its hinges.
