Understand the role levers play in our everyday lives. Learn what is a lever is, identify the classes of levers, and see examples.
These types include: 1. First-class lever: In a first-class lever, the fulcrum is located between the force and the load. This type of lever can either amplify force or increase distance, depending on the placement of the fulcrum. Examples of first-class levers include seesaws and scissors...

The Three Types of Levers There are three different kinds of levers: first class, second class, and third class. Each of these lever classes have unique arrangements of the muscle’s insertion (effort) and bones (lever/arm) around the joint (fulcrum). See the chart below to visualize the...
Examples of Class 3 levers include: Tweezers Stapler Mousetrap Broom Hockey stick Stapler is Class 3 lever Summary There are three types or classes of levers, according to where the load and effort are located with respect to the fulcrum. Class 1 has the fulcrum placed between the effort and...

Types of Levers When using a lever to perform work, we focus not on masses, but on the idea of exerting an inputforceon the lever (calledthe effort) and getting an output force (calledthe loadorthe resistance). So, for example, when you use a crowbar to pry up a nail, you are ex...

There are three types of levers depending on the relative positions of the fulcrum, the effort and the load (or resistance). The formula of the law of the lever above is the same for all three classes of levers. Class 1 Levers: The fulcrum is between the effort and the load, which ar...
