Summary[edit]

Description
English: A funicular polygon is obtained by replacing the object by a truss linking the points where the force apply. The equilibrium at each node gives a polygon of forces, the global polygon of forces is obtained by putting together all the polygons. The pole is point that is common to all polygons. For the resolution of problems, a pole is taken outside the polygon of forces, and the nodes of the truss are different from the application points (the moment arm does not change when the force is applied at another point of its supporting line).
Français : On obtient un funiculaire en remplaçant l'objet par un treillis reliant les points d'application des forces. L'équilibre à chaque nœud se traduit par un polygone des forces. On obtient le dynamique en rassemblant les polygones des forces. Le point commun des polygones est le pôle. Pour la résolution d'un problème, on choisit un pôle en dehors du dynamique, et les nœuds du treillis ne correspondent plus aux points d'applicaiton des forces (le moment d'une force ne change pas si on l'applique à un autre point de sa droite d'application).
