The Law of the Lever formula is (E)(R) = (L)(r), where E is the effort force, R is the lever arm connected to the effort, L is the load, and r is the lever arm connected to the load. Be sure to measure the lever arms, R and r, from the points on the lever arms that...
An example: calculate the lever arm to lift the world We can calculate the characteristics of a lever able to lift the world using the lever equation. There's only a condition: you're the one doing the lifting! Assuming a weight of 70 kg70 kg and that you're standing on your end of...
This example has been based upon the idea of masses sitting on the lever, but themasscould be replaced by anything that exerts a physical force upon the lever, including a human arm pushing on it. This begins to give us a basic understanding of the potential power of a lever. If 0.5M2=...
In the first-class lever, the full length of the lever L equals to the sum of the load arm AL and the effort arm AE: The load arm formula (and the fulcrum position) is derived from the law of the lever formula above: Class 2 Levers: The fulcrum and the effort are located on the...
