Abstract
Élément de poids intermédiaire (10) de section variable et dont le moment de flexion d'inertie varie en fonction de l'emplacement sur la longueur de l'élément. Une des extrémités de l'élément (10) comporte une section de glissement et de profondeur (14). Une section partiellement rainurée (16) de diamètre supérieur à celui de la section de glissement et de profondeur constitue la partie comprise entre la section de glissement et de profondeur (24) et l'autre extrémité de l'élément (10). La partie partiellement rainurée (16) comporte deux sections de rainurage de profondeur variable (18 et 20) séparées par une section non rainurée (22). La section non rainurée (22) comporte des bagues de bordage (26 et 28). Les rainures hélicoïdales (30A, 30B et 30C) des sections de rainurage de profondeur variable (18 et 20) varient en profondeur en fonction de l'emplacement sur la longueur de l'élément, de la même façon que le moment de flexion d'inertie est fonction de la distance entre la section de glissement et de profondeur (14) et l'extrémité inférieure de l'élément (10). Ces variations vont d'un moment de flexion d'inertie constant au niveau de la section de glissement et de profondeur (14) à un moment de flexion d'inertie significativement plus élevé au niveau de la section non rainurée (22), et à un moment de flexion d'inertie plus bas au niveau de la section de diamètre réduit (24) à l'autre extrémité de l'élément.
