of thesingle fixed pulley is 1, that of the single movable pulley is2, that of the system of pulleys shown in Fig. 116 is 6, etc. If the acting force is applied at B instead of at E the me-chanical advantage of the systems of pulleys of Fig. 116 is i;for it requires an application of 6 pounds at B… … Fig. 116. Combinationsof pulleys 110 WOEK AND MECHANICAL ENERGY sacrifice force to gain speed; but in every case, whatever wegain in the one we lose in the other. Thus in the hydrauhcelevator shown in Fig. 13, p. 18, the cage moves only as fastas the piston ; but in that shown in Fig. 14 it moves…
