t right angles. The foregoing two articles apply equally well to the forces on the right of any segmentif the system is a balanced one. The sign of the moment, or the direction in which it tends to turn about the point, is atonce seen when we remember that the segment is the line of action of the… … Fig. 36. 37. Forces Parallel or Nearly so.—Given the forces , and (Fig. 36); re-quired their resultant. The force polygon {p) gives their resultant, 1-5,in amount and direction ; 5-1 is a force which willbalance the given system. Resolve this force into anytwo components, P and P\ by drawing the…
