Across
- 2. force- The amount of force applied to applied to a machine
- 5. and axle- Combination of two wheels that have different diameters that turn together.
- 7. force- The amount of force that a machine applies to an object.
- 9. Part that transfers your energy from the pedals back to the wheel.
- 10. radio- A measure of how the speed of the object travels in a given amount of time.
- 11. a device that helps us do work
- 13. Essential components of most mechanical systems. These consist of wheels and teeth that interlink.
- 15. system- uses a liquid under pressure to move loads. This increases the mechanical advantage of levers and machines.
- 16. To transfer energy from the engine to the wheels.
- 18. machines- Made up of more than one type of simple machine
- 19. Consists of wire, rope, or cable moving on a grooved wheel.
Down
- 1. pulleys- Fastened to one spot and does not move. It does not offer an increase in force.
- 3. plane or ramp would make it easier for you to move the box up onto the desk.
- 4. Groups of parts that perform a specific function such as breaking or steering.
- 5. similar shape to an inclined plane but it is used in a different way. The wedge machine is forced into an object.
- 6. mechanical advantage- You can calculate this if the mechanical advantages of a machine if you know the input and output forces. The mechanical advantage equals the output force divided by the input force.
- 8. A rigid bar or plank that can rotate around a fixed point called a pivot or fulcrum.
- 12. advantage- The amount by which a machine can multiply by a force.
- 14. Measurement of how well a machine or device uses energy
- 17. A cylinder with a groove cut in a spiral on the outside.
