Moment: [...]\text{[...]}[...], where ddd is perpendicular to the line of action. Its SI unit is N m.
For a force at angle θ\thetaθ, the perpendicular distance is d=rsinθ\boxed{d=r\sin\theta}d=rsinθ, giving the moment M=FrsinθM=Fr\sin\thetaM=Frsinθ.
The moment doubles.

Moment: M=Fd\boxed{M=Fd}M=Fd, where ddd is perpendicular to the line of action. Its SI unit is N m.
