1. Pulleys in Everyday Life
Let’s look at some places we use pulleys

2. CONSTRUCTION A crane uses a single pulley Uses gears to help
move the crane around

3. MECHANIC
Uses pulley to lift heavy items out of cars

4. CAR ENGINE
This is a serpentine belt that moves around inside an engine to help a car move; it moves on pulleys

5. LOADING DOCKS
Machines similar to cranes help lift and lower large shipping containers onto and off of ships

6. WELL In many places where there is no water, they use a well
Pulley is at the top and used to lift and lower water bucket

7. GYM
Weight machines have visible pulleys to help lift and lower the weights
Other machines like a treadmill or stationary bike also use pulleys to allow the parts to move

8. CLOTHESLINE
Many people choose to hang their laundry to dry instead of using a dryer
Pulley system allows them to hang clothes on the line, and pull the rope along to get empty rope or collect the dry clothes

9. TOW TRUCK Uses a pulley on the hitch to lift cars

19. Pulleys are used in many ways all around us!
Without them, some tasks would be much more difficult or could not happen at all!
Pulleys allows lifting, lowering, and some movement to be made easier
Pulleys must be strong and not produce too much friction for the cables passing over them
Pulleys can be fixed (attached to something) or not
Combining pulleys requires less force (more pulleys = less work)
