Since a force 4 0 will balance 0 4, a force rep-resented in magnitude and direction by the line 4 0will, together with the five given… … Fig. 22 equal in magnitude and parallel to ab (Fig. 22). Fromb draw bc equal and parallel to b c; continue the pro-cess, taking the forces in order. It will be found bydrawing the closing line of the polygon, that is, byjoining x to a, that xa gives the magnitude and thedirection of the force…
