Definition

vector (ISO 80000-2: Mathematics) quantity described by the vector product:

$M = r \times F$

where $r$ is position vector (ISO 80000-3: Space and time) with respect to the axis of rotation and $F$ is force (force)

grandeur vectorielle définie par le produit vectoriel :

$M = r \times F$

où $r$ est le rayon vecteur (ISO 80000-3: Space and time) par rapport à l'axe de rotation et $F$ est la force (force)
