उत्तर
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
- Seesaw: A common playground equipment.
- Scissors: Both handles and blades operate as Class 1 levers.
- 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.
