Summary edit

Description
English: Graphical method used to solve static problems:
  1. the forces are drawn on the right side to make a closed polygone (dynamique means polygon of forces);
  2. a pole P is chosen; the lines 0, 1 and 2 are drawn from P to the angles of the polygone;
  3. the lines 0', 1' and 2' are parallel to 0, 1 and 2 respectively, and link the lines of the forces: the line 1 is common the F1 and F2, so 1' links the line of F1 with the line of F2 (funiculaire means funicular polygon).
This drawing is useful when forces and/or vector lines are unknown.
Français : Méthode de statique graphique :
  1. On trace les forces du côté droit pour former un polygone fermé (dynamique) ;
  2. On choisit un pôle P ; les segments 0, 1 et 2 relient P anx angles du polygone ;
  3. les droites 0', 1' et 2' sont parallèles à 0, 1 et 2 respectivement, et relient les lignes d'action des forces : le segment 1 est commun à F1 et F2, donc 1' relie les droites d'action de F1 et de F2 (funiculaire).
Cette méthode est utile lorsque l'on ne connaît pas certaines forces et/ou certaines lignes d'action.
