s (2) will sufiice to fixthe position of the resultant of the system; for let one of the axes,as the axis of z, be taken parallel to the direction of the forces,then, as the resultant itself will be parallel to the same axis, itsposition will be known if we only know where it meets the planeof xy,… … PARALLEL FORCES. 57 whatever point in this line it acts, the effect is the same. Under thisarrangement of the axes, therefore, the equations necessary for thedetermination of the resultant in intensity and position are R=P+P,+P,H-P3+ • 1 RX=Pa;+Pi X1+P2 x^+Ps x^-h Y • • (3).RY=Py+P, 2/1+P. 2/. + P3…
