WEBExample - First-Class (Order) Lever - A force (weight) of 1 pound is exerted at the end of a lever at distance 1 ft from the fulcrum. The effort force at a distance of 2 ft from the fulcrum can be calculated as. F e = (1 lb) (1 ft) / (2 ft) = 0.5 (lb) The formula (1) can be modified to express required load if you know the effort, or required distance from fulcrum if load and …

WEBApr 2, 2024 · For a class I lever, calculate the distance dr of the fulcrum from the load using dr = L / (MA + 1). For a class II lever, determine the distance dr of the fulcrum from the load using dr = L / MA. For a class III lever, the distance dr of the fulcrum from the load is equal to the length of the lever, dr = L.
