3. purpose or task
5. when pressure is applied to a liquid in a container, the pressure and force is transmitted equally and undisminished throughout the liqud
8. force that opposes motion
10. pair of wheels with teeth that interlink
11. (of a machine) smaller group of paerts within a complex machine that performs a specific function
13. force applied to operate machine
15. measure of how speed of the object is affected by a machine
17. done when a froce acts on an object to make the object move
18. simple machine made up of two wheels of different diameters that turn together
19. A lever in which the fulcrum is positioned between the load and the effort
20. simple machine made up of a flat surface, such as a board, at an angle to another flat surfaace, such as the ground or a table top
22. a plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is built or made.
24. measure of the amount of force applied to a given area

1. device that helps us do work
2. measurement of how well a machine or device uses energy
4. belt or chain to transfer energy from an energy source to an object
6. tool or device made up of one basic machine
7. system in wich simple machines all work together
9. force a machine applies to an object
12. amount by which a machine can multiply force
14. system that uses liquid under pressure to move loads
15. simple machine that consists of a cylinder with a groove cut in a spiral on the outside
16. special type of linkage for transferring the energy from the engine to the wheels in large vechicles such as cars and trucks
21. (in context of machine) a group of parts that work together to perform a general function, forming a complex machine
23. simple machine made up of a wire, rope, or cable moving on a grooved wheel
