Simple Machines by Mind Map: Simple Machines

1. Work

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

1.2. W=FD

1.3. Joules

1.4. The work of a car

1.5. The work of a train

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

2. Power

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

2.2. P=W/T

2.3. Watts

2.4. The power of a car

2.5. The power of a train

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

3. Mechanical Advantage

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

3.2. MAF = FL/FE

3.3. There is no unit

3.4. Lever or Screw

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

4. 1st class levers

4.1. 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.

4.2. Crowbar, Fixed Block

4.3. 1st class levers are simple machines

5. 2nd class levers

5.1. 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.

5.2. Wheel barrow

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

6. 3rd class levers

6.1. 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.

6.2. Basbeball bat

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

7. Incline Planes

7.1. 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.

7.2. Ramp

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

8. Wheel and axel

8.1. 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.

8.2. A system using a wheel to help move it

8.3. This relates to simple machines because it is one

9. Wedge

9.1. 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.

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

9.3. This relates because it is a simple machine

10. Screw

10.1. 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.

10.2. A metal screw

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

11. Pulley

11.1. 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.

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

11.3. This relates to simple machines because it is one
