The Funicular Polygon.—When a series of forces in the sameplane do not act at the same point, but so as to stretch anendless cord at different points, the polygon formed by the cordthen in equilibrium is called the funicular… … Fig. 350. EC to q; CD to r; DE to s ; and EA to t. Assume any point0 in this polygon,—this is called the pole,—and join each of theangles of the polygon to it. These lines are called vectors.
