Definition

geometrical characteristic of a shape of a body equal to:

$Z = I_{a} / r_{Q,max}$

where $I_{a}$ is the second axial moment of area (second axial moment of area) and

$r_{Q,max}$ is the maximum radial distance (ISO 80000-3: Space and time) of any point in the surface considered from the $Q$ -axis with respect to which $I_{a}$ is defined

caractéristique géométrique de la forme d'un corps, égale à :

$Z = I_{a} / r_{Q,max}$

où $I_{a}$ est le moment quadratique axial d'une aire plane (second axial moment of area) et $r_{Q,max}$ est la distance radiale maximale (ISO 80000-3: Space and time) d'un point quelconque de la surface considérée à l'axe $Q$ par rapport auquel $I_{a}$ est défini
