In the picture below the distance between the load and fulcrum is 2 m. The distance between the effort and fulcrum is 6 m. Therefore, the mechanical advantage = 6 ÷ 2 = 3 or 3:1 The person will ...

In the picture below the distance between the load and fulcrum is 2 m. The distance between the effort and fulcrum is 6 m. Therefore, the mechanical advantage = 6 ÷ 2 = 3 or 3:1 The person will ...

It explains how the position of the fulcrum affects the amount of force needed to lift a load and demonstrates various applications of levers in tools such as shovels, hammers, scissors ...
