Simple Machines

1. 1st class levers

1.1. A lever in which the fulcrum is positioned between the load and the effort

1.2. Crowbar, wedge

1.3. They relate to a simple machines because it moves the object

2. 2nd class lever

2.1. A lever in which the load lies between the fulcrum and the effort

2.2. wheel barrow, bridge

2.3. They relate to simple machines by just changing the place of the fulcrum

3. 3rd class lever

3.1. Third-class levers have the effort placed between the load and the fulcrum. The effort always travels a shorter distance and must be greater than the load.

3.2. Chopsticks, Paperclip

3.3. They relate to simple machines by not being to complicated

4. incline planes

4.1. also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.

4.2. A ramp, a slope

4.3. They relate to simple machines by just moving the load

5. wedge

5.1. a piece of a substance (as wood or iron) that tapers to a thin edge and is used for splitting wood and rocks, raising heavy bodies, or for tightening by being driven into something

5.2. A door wedge, A cheese wedge

5.3. Relates to simple machines by not being complicated

6. screw

6.1. a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place. synonyms: bolt, fastener

6.2. Screw, Nail

6.3. Relates to simple machines by holding things in place

7. Wheel and Axle

7.1. a machine or structure having a wheel as its essential part.

7.2. Motor, bike

7.3. relates to simple machines because you can use it in different ways

8. Pulley

8.1. hoist with a pulley

8.2. A swing, a rappel

8.3. relates to simple machines by lifting

9. Work

9.1. activity involving physical or mental effort done in order to achieve a goal

9.2. F x D x cos

9.3. Newton

9.4. Weight lifting

9.5. Apply the same force they lift

10. Power

10.1. the ability to do something or act in a particular way, especially as a faculty or quality.

10.2. F x D / T

10.3. Watt

10.4. A lightbulb

11. Mechanical advantage

11.1. he ratio of the force produced by a machine to the force applied to it, used in assessing the performance of a machine.

11.2. MA = output force / input force

11.3. Bicycle chain

11.4. They relate to simple machines because it helps lift something
