Mechanisms

3. A twisting force/Force in a circular direction
4. The application of force that moves an object a certain distance.
7. A push or pull on an object in a straight line
9. A threaded shaft used to convert rotary movement to linear movement.
10. A swing back and forth at a regular rate.
12. The results of the operation of any system.
13. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.
14. Opposite in position, direction, order or effect.
16. The ability to do work/what do you need to do work?
17. The ratio of the speed of the driving member of a gear train to that of the driven member.
19. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.
22. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.
24. A joint that allows connected shafts to spin freely while permitting a change in direction.

1. The gear that transmits power and motion to the rest of the system. The input gear.
2. A back-and-forth movement in a straight line
5. Movement in a circle motion or one direction in an arc
6. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.
8. One of a pair of gears used to connect two shafts whose axes intersect.
11. A gear between the driver and the driven gear used to change rotational direction.
15. Gear The member of a pair of gears to which motion and power are transmitted by the other. The output gear.
18. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
20. Something put into a system, such as resources, in order to achieve a result.
21. Movement in one direction in a straight line.
23. The distance between adjacent threads in a screw.
