The sides of the force-polygon may in the first instance be arranged in any order; the force-diagram can then be completed in a doubly infinite number of ways, owing to the arbitrary position of 0; and for each force-diagram a simply infinite number of **funiculars** can be drawn.

If **funiculars** be drawn for two positions 0,0 of the pole in the force-diagram, their corresponding sides will intersect on a straight line parallel to 00.

The complete figures obtained by drawing first the force-diagrams of a system of forces in equilibrium with two distinct poles 0, 0, and secondly the corresponding **funiculars**, have various interesting relations.

.and A, B, C, of the two **funiculars** draw normals to the plane of the diagram, to meet w and w respectively.
