Types of Levers with Examples

Sunday, December 25, 2022

Levers are simple machines that we use in everyday life.

 Levers include three main objects, an effort,a load, and a fulcrum.

The fulcrum is the object in which the force pivots.

Levers also cpme in three classes, first,second, and third class,

An easy way to remember the different classes is to use FLE then 123.

  • The F stands for Fulcrum.
  • The L stands for Load
  • The E stands for effort.

The 1,2, and 3 stand for the different classes.

You then look for what is in the middle. 
If the fulcrum is in the middle it is a 1st class lever.
