Learn How Pulleys Make Lifting Easier

Pulleys are simple machines that change the direction of force needed to move objects, making lifting heavy items more manageable. By utilizing wheels, axles, and ropes, pulleys allow for efficient lifting and lowering of loads. Explore the types of pulleys and examples of their use in daily life, enhancing your understanding of this essential mechanical tool.

4. What is a pulley? Pulley: a simple machine that is used to change the direction you have to apply force to move an object The more pulley s you put together, the easier it becomes to move

5. They work by using a wheel, an axle, and a rope wheel rope axle

6. The axle holds the wheel in place The wheel allows the rope to move around it smoothly The rope is pulled across the wheel and axle, making it easy to lift objects attached to the other side force load

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

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

9. Pulleys are used when objects are too large or difficult to pick up by hand Using a pulley allows you to change the direction you lift to move an object

10. Instead of trying to lift an object from the side, a pulley will allow you to lift it from the top This allows you to pull the object up with more strength because you can get all of your weight into it!

11. Types of Pulleys Fixed Pulley: this type of pulley is attached to a supporting structure and stays in place Movable Pulley: this type of pulley is able to move with the object being lifted Compound Pulley: this is when 2 or more pulleys are put together

12. Types of Pulleys fixed compound moveable

13. Compound Pulleys The more pulleys you put together, the higher the mechanical advantage of the pulley system Each extra pulley in a pulley system helps reduce effort needed by 1

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