Simple Machines

1. Power

1.1. supply (a device) with mechanical or electrical energy.

1.2. P=W/T

1.3. Watts

1.4. The power of a car

1.5. The power of a train

1.6. This relates to simple machines because it represents how much power they have

2. Mechanical Advantage

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

2.2. MAF = FL/FE

2.3. There is no unit

2.4. Lever or Screw

2.5. Mechanical advantage relates to simple machines because simple machines give you mechanical advantages.

3. 2nd class levers

3.1. A lever in which the load lies between the fulcrum and the effort. A wheelbarrow is an example of a second-class lever. see saw. A long, narrow board equally balanced in the middle on a fulcrum.

3.2. Wheel barrow

3.3. These are simple machines so that's how they relate

4. Wedge

4.1. a piece of wood, metal, or some other material having one thick end and tapering to a thin edge, that is driven between two objects or parts of an object to secure or separate them.

4.2. A piece of metal in the shape of a wedge

4.3. This relates because it is a simple machine

5. Screw

5.1. a metal fastener having a tapered shank with a helical thread, and topped with a slotted head, driven into wood or the like by rotating, especially by means of a screwdriver.

5.2. A metal screw

5.3. Thus relates to simple machines because it is a simple machine

6. Pulley

6.1. a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.

6.2. A rope with a wheel that spins around. Used to lift heavy objects

6.3. This relates to simple machines because it is one

7. Work

7.1. (of a machine or system) operate or function, especially properly or effectively.

7.2. W=FD

7.3. Joules

7.4. The work of a car

7.5. The work of a train

7.6. This relates to simple machines because work shows how effective a machine is

8. 1st class levers

8.1. The force applied to an object or machine to cause motion. first-class lever. A lever in which the fulcrum is positioned between the load and the effort. A crowbar is an example of a first-class lever. fixed block.

8.2. Crowbar, Fixed Block

8.3. 1st class levers are simple machines

9. 3rd class levers

9.1. third-class lever. A lever in which the effort is placed between the fulcrum and the load. A baseball bat is an example of a third-class lever.

9.2. Basbeball bat

9.3. This relates to a simple machine because it is one

10. Incline Planes

10.1. An inclined plane, 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.

10.2. Ramp

10.3. This relates to a simple machine because it is a simple machine

11. Wheel and axel

11.1. a simple lifting machine consisting of a rope that unwinds from a wheel onto a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.

11.2. A system using a wheel to help move it

11.3. This relates to simple machines because it is one
