From the figure we see that the maximum effort of the engine in the first case is muchless than in the second—which proves that the ram is a better form of Hft than the screw. The dotted curve Oad represents the curve of effort for an end lift,… … Fig. 401. the horizontal bar H the ram is not as efficient as the screw, for which the curve of efYort isrepresented by the straight line Oe. These curves were all plotted from actual examples, and clearly show the advantage inusing the ram as compared with any other known form of end lift. For any…
