Across
- 3. measure of amount of force applied to a given area
- 5. simple machine that looks like an inclined plane but is forced to an object
- 7. pair of wheels with teeth that interlink when they rotate together, one gearwheel transfers turning motion and force to the other
- 9. force applied to operate a machine
- 11. simple machine that consists of a cylinder with a groove cut in a spiral on the outside
- 13. measurement of how well a machine or device uses energy, can be calculated by dividing mechanical advantage by speed ratio or dividing work output by work input
- 14. a group of parts that work together to perform a general function forming a complex machine
- 15. amount by which a machine can multiply a force, calculated by dividing the output force by the input force
- 18. when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid; an enclosed liquid transmit pressure equally in all directions
- 21. simple machine made up of two wheels and different diameters that turn together
- 22. force that opposes motion
- 24. force a machine applies to an object
Down
- 1. system that uses a liquid under pressure to move loads, device that uses liquids in a confined space to transfer forces, works according to pascal's law
- 2. is the physical form of the device that makes it usable
- 4. tool or device made up of one basic machine
- 6. done by when a force acts on an object to make the object move, calculated by multiplying force times distance
- 8. smaller group of parts within a specific complex machine that performs a specific function
- 10. simple machine made up of a flat surface, such as a board, at an angle to another flat surface, such as the ground or a table top
- 12. special type of linkage for transferring the energy from the engine to the wheels in large vehicles such as cars and trucks
- 16. a machine made up of several parts
- 17. belt or chain to transfer energy from an energy source to an object
- 19. simple machines made up of a rigid bar or plank that rotates on a fixed object called a pivot or fulcrum
- 20. measure of how the speed of the object is affected by a machine, calculated by dividing the input distance by the output distance
- 23. simple machine made up of a wire, rope or cable moving on a grooved wheel. May be made up of one or many wheels.
- 25. in hydraulic system, the pressure is created using this
