La marge statique correspond à la valeur algébrique de la distance entre les projections du centre de gravité et du foyer aérodynamique d’un avion sur une corde de référence longitudinale, exprimée en pourcentage de la longueur de cette corde, et considérée comme positive lorsque le foyer est en arrière du centre de gravité. 2, record 2, French, - marge%20statique

C’est à partir d’un point de référence appelé « foyer » que dépend la stabilité d’un avion. La position du CG [centre de gravité] par rapport au Foyer détermine sa stabilité ou sa maniabilité. [...] Le foyer est le point d’application des variations de la portance. L’une des propriétés du foyer est que sa position est fixe, contrairement au point d’application de la portance qui est toujours appliqué au centre de gravité, et dont la position varie en fonction de la répartition des masses fixes et mobiles de l’avion. 4, record 2, French, - marge%20statique

Principles of gyroscopic action. ... Dynamic stability. When the cone sits on its base on a flat surface and is tipped slightly, it returns to its original position when the tipping force is removed. This is said to be a statically stable position. If the cone is turned over, it may momentarily be possible to balance it on its pointed end, but the slightest tipping force will make it fall on its side. The latter position is said to be statically unstable. 2, record 3, English, - statically%20stable%20position

The aim of this section is to calculate the torques which have to be generated in the leg joints to hold the leg in a statically stable position. Dynamic forces will not be taken into consideration, since all movements of the robot are slow. First, the torques will be calculated as functions of the leg geometry, position, and the weight to be supported by the leg. Afterwards, these general expressions will be evaluated for a real robot leg. 3, record 3, English, - statically%20stable%20position
