### Simple machines powerpoint

1. 1. Simple Machines<br />By: Angie Barnas<br />
2. 2. Examples of the 6 Types of Simple Machines<br />Wedge<br />Wheel and Axle<br />Lever<br />Inclined Plane<br />Screw<br />Pulley<br />
3. 3. Wedge<br />Pushes materials apart; cuts things<br />I found a knife in my house located in the kitchen cabinet<br />I also found a fork in my house located in the kitchen cabinet<br />
4. 4. Wheel and Axle<br />Makes it easy to move by rolling them and reducing friction.<br />I used my mom’s car as an example because when driving it, the wheels are rolling and reducing the friction<br />I used my bike as an example of wheel and axle because when riding my bike, the wheels are spinning and reducing friction<br />
5. 5. Lever<br />Makes lifting weights easier by using a fulcrum to redirect force over a longer distance.<br />To show an example of a lever I used my dad’s saws. First one is called a skil saw.<br />Another example is a Chain Saw. I also found this in my garage where my dad keeps all of his saws. <br />
6. 6. Inclined Plane<br />Makes it easier to move objects upward, but you have to go further horizontally.<br />The first example of an inclined plane are the stairs in my house. Its easier to go downstairs than upstairs because your going horizontally.<br />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<br />
7. 7. Screw<br />Turns rotation into lengthwise movement, takes many twists when going a short distance and it also holds many things together.<br />My first example of a screw is a screw. I found the screw in my garage where my dad keeps all of his stuff.<br />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. <br />
8. 8. Pulley<br />Makes lifting things with a rope a lot easier.<br />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.<br />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<br />
9. 9. Compound Machines<br />Consists of two or more simple machines put together.<br />I found scissors in my house that are an example of a compound machine.<br />I also found a bike at my house that is an example of compound machines. <br />
10. 10. Summary<br />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. <br />
