aving been put in, then consider the case in Fig. 45 in oneplane. If we take any point, p, on the cord as a centreof moments, knowing that the resultant P, of the forces PirjPa, and P%, situated on one side oip, must act along the cord through p (by Prin. 1), thereforewe have Pxay — P7aa — P^v^ = P… … STATICS OF FLEXIBLE CORDS. 43 merits of those forces situated on one side {either) of this pointwill equal zero. 41. The Pulley.—A cord in equilibrium over a pulley whoseaxle is smooth has the same tension on both sides; for, Fig. 46,
