hepower P or the weight W, and then using the proper equation.^^^^ For instance, in example 1, ^•-^^ Art. 54, it was found thata force of 500 pounds at Pwould balance 1,000 poundsat Tf, the lever arms being20 inches and 10 inches,respectively. Now, to findthe force sustained at F,assume the fulcrum… … TT = 1,500 pounds. This, it will be noticed, is equal to the sum of the power Pand the weight W. If this method is applied to the three classes of levers, it willbe found that (1) the c pressure on the fulcrum ,- \ of a lever of the first ,-- \ class is equal to the v- \ sum of the power andthe…
