EXAMPLES OF THE 6 TYPES OF SIMPLE MACHINES Wedge Wheel and Axle Lever Inclined Plane Screw Pulley

WEDGE Pushes materials apart; cuts things I found a knife in my house located in the

kitchen cabinet

I also found a fork in my house located in the kitchen cabinet

WHEEL AND AXLE Makes it easy to move by rolling them and reducing

friction. I used my mom’s car as an example because when

driving it, the wheels are rolling and reducing the friction

I used my bike as an example of wheel and axle because when riding my bike, the wheels are spinning and reducing friction

LEVER Makes lifting weights easier by using a fulcrum to

redirect force over a longer distance. To show an example of a lever I used my dad’s saws.

First one is called a skil saw.

Another example is a Chain Saw. I also found this in my garage where my dad keeps all of his saws.

INCLINED PLANE Makes it easier to move objects upward, but you

have to go further horizontally. The first example of an inclined plane are the stairs

in my house. Its easier to go downstairs than upstairs because your going horizontally.

Another example that I used is a sidewalk ramp. I couldn’t find a sidewalk ramp around my house so I used an outside source. http://www.windycitizen.com/files/cuts4.jpg

SCREW Turns rotation into lengthwise movement, takes

many twists when going a short distance and it also holds many things together.

My first example of a screw is a screw. I found the screw in my garage where my dad keeps all of his stuff.

Another example is a jar lid. The jar lids turn rotation into lengthwise movement. I found a jar in a kitchen cabinet so I used to jar lid.

PULLEY Makes lifting things with a rope a lot easier. I used a flag pole as an example. I found a flag pole

outside my house and I thought it was a good idea to use it as an example of a pulley.

Another example that I used were window shades/blinds. I don’t have window shades/blinds at home so I used an outside source. http://www.jamesfloors.net/image/county%20woods.png

COMPOUND MACHINES Consists of two or more simple machines put

together. I found scissors in my house that are an example of

a compound machine.

I also found a bike at my house that is an example of compound machines.

SUMMARY All these objects are examples of simple and compound

machines. The 6 types of simple machines are wedge, wheel and axle, lever, inclined plane, screw, and a pulley.
