Question

The diagram given below shows the three kinds of levers. Name the class of lever and give one example of the class.

Answer 1

The provided diagram shows a lever system with the fulcrum, load, and effort clearly labeled.

Class of Lever

This is a Class 1 Lever, where the fulcrum is positioned between the load and the effort.

Examples of Class 1 Lever

1. Seesaw: A common playground equipment.
2. Scissors: Both handles and blades operate as Class 1 levers.
3. Crowbar: Used for prying objects.

How It Works:

• In a Class 1 lever, the effort and load move in opposite directions around the fulcrum.
• Depending on the position of the fulcrum, the lever can be used to gain either a mechanical advantage (make lifting easier) or speed advantage.
