- Title
How a Lever Works.
- Abstract
The article offers information on how to use a lever in lifting heavy objects. A very simple lever can be made from a long board placed over a pivot point, with one end of the board under the object that needs to be lifted. The long board that is under the load is called liver arm, a part that is placed over an object so that the lever arm will pivot. The position of the load and the effort, a term used to describe the force to the lever, can be changed and moved around in any order on the lever. As long as the position of the pivot point or fulcrum stays between the effort force and the load, the lever is considered a first-class lever.
