Types of Levers
There are three classes of levers:
- First-Class Lever: In this type of lever, the fulcrum is located between the effort (the force you apply) and the load (the weight you are lifting). An example is a seesaw.
- Second-Class Lever: In this type, the load is between the fulcrum and the effort. A good example is a wheelbarrow.
- Third-Class Lever: In this type, the effort is between the fulcrum and the load. An example of this is a pair of tweezers.
