A^,they must meet in a point O, andfulfil the parallelogram law. After turning each force about itspoint of application by the sameangle, the forces will, in general,cease to intersect in a point, andhence to be in equilibrium. If, however, the original meetingpoint O of the forces be situated on… … 159-] STABILITY. gj Hence, three forces Fj, Fj, Fg in the same plane, applied atpoints Aj, Aj, Ag, are in astatic equilibrium if they meet in apoint O situated on the circle passing through A^, Ag, Ag. The condition of equilibrium of the three forces also requires that ^1 - ^2 _ ^s . sin {F^F^ sin…
