uilib-rium, that is, if the resultant of three forces is zero, the threeforces must meet at a point, they must lie in one plane, andthey must be represented in intensity and direction by the threesides of a triangle taken in order; that is, each force must be FORCE AND MOTION. equal and opposite to… … Fig. .50. Eqiiilibi-iuin of three forces. forces acting at point A, AD is their resultant, being the diag-onal of the parallelogram founded upon AB and AC as sides.In order to hold these two forces in equilibrium, that is, inorder to have a zero resultant, it is necessary to add the thirdforce AD%…
