What a Lever is
A lever is one of the most simplest machines. They are helpful for lifting heavy loads. This machine may be simple but there are still many parts working to make this simple machine useful.
The Parts of a Lever
There are 3 parts of a lever. There is the fulcrum, which steadies out the lever. There is the load, which weighs the lever down. And there is the effort, which pushes against the load.
1st Class Lever
This is where the pivot is between the effort and the load.
2nd Class Lever
This is where the load is between the fulcrum and the effort.
3rd Class Lever
