ne. (Why?) Raise W, andmeasure the distance traversed respectively by P and W. P movesonly two ft. for every 4 ft. that W moves. Now, 2 (ft.) X IG (lbs.) =32 foot-pounds of work done by P. And 4 (ft ) X 8 (lbs.) =32 foot-4)ounds of work done upon W. We thus learn that, when the power isemployed in… … 144 LAW OF MACHINES. Fig. 97 by the use of apparatus? We found that W moved twice as farand, coiisequeutly, witli twice the velocity, th;it P moved. It thus appears that, if it should be desirable to move a weight withgreater velocity than It is possible or convenient for the power tomove, it may…
