Simple Machines

By Vanessa, Hanna and Malik

This is an example of an inclined plane. A real world example is a wheelchair going up a ramp. This helps people who can’t walk up stairs. It allows you to push instead of carry because the ramp is connected to the top of the stairs so all you have to do is ride up the ramp. If you carry you are using a lot of energy.

This is an example of a lever. A real world example is a hammer. The hammer is putting a nail in a board. This makes it easier to hang things in your house. As apposed to hanging with tape or string, the thing you’re hanging will stay up longer.

This is an example of a pulley. A real world example is the American Flag’s rope. The guy pulls the rope and it makes the flag rise in the air. If you didn’t have the rope, then you will have to climb or use a ladder.

This is an example of a screw. The real world example is a light bulb. At the bottom of a light bulb, is a screw. It helps the light bulb stay in it’s place. The light bulb would just fall off.

This is an example of a wedge. The real world example is a door stopper. The wedge helps stop the door from moving. You wouldn’t have to keep holding the door to go through.

This is an example of a wheel and axle. A real world example is a bike. The wheel in the front of the bike is a example of this simple machine. It helps the bike move.
