Understanding Levers: Simple Machines for Lifting Heavy Objects

Levers are essential simple machines that help in lifting heavy objects by changing the direction of force needed to move an object over a fulcrum. These tools work by using a strong beam that pivots at a point called the fulcrum, spreading the weight of the object across a longer distance. There are different types of levers depending on the location of the fulcrum, such as First Class, Second Class, and Third Class Levers. Examples of levers in daily life include using them when objects are too heavy to lift by hand. By utilizing a lever, you can lift objects with more strength and mechanical advantage.

4. What is a lever? Lever: a simple machine that is used to change the direction of force needed to move an object over a fulcrum (pivot point) The different kinds of levers depend on where the fulcrum is located

5. They work by using a strong beam that pivots at a point called the fulcrum beam fulcrum

6. The beam spreads the weight of the object across a longer distance The fulcrum is where the beam pivots, creating leverage, making it easier to lift objects on other side load force beam fulcrum

7. What are some examples of levers you might see in your daily lives?

8. What are some examples of levers you might see in your daily lives?

9. Levers are used when objects are too heavy to pick up by hand Using a lever allows you to change the direction you apply force to move an object over a pivot point

10. Instead of trying to lift an object from the side, a lever will allow you to lift it across a beam This allows you to lift the object up with more strength because you can get all of your weight behind it! The longer the beam, the greater the mechanical advantage!

11. Types of Levers First Class Lever: the fulcrum is located in between the effort and load Second Class Lever: the load is located in between the effort and fulcrum Third Class Lever: the effort is located in between the fulcrum and load

12. Types of Lever: First Class example

13. Types of Lever: Second Class example

14. Types of Lever: Third Class example

15. Lets try it! Use different types of levers to lift different weights! Write down your observations
