Mechanical Systems

2. The application of force that moves an object a certain distance.
4. A joint that allows connected shafts to spin freely while permitting a change in direction.
5. A gear between the driver and the driven gear used to change rotational direction.
9. Movement in a straight line.
12. Something put into a system, such as resources, in order to achieve a result.
13. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.
14. A twisting force.
15. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.
17. Circular movement.
20. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.
22. A push or pull on an object.
24. A back and forth movement.
26. The results of the operation of any system.
27. One of a pair of gears used to connect two shafts whose axes intersect.

1. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.
3. A swing back and forth at a regular rate.
6. The gear which transmits power and motion to the rest of the system. The input gear.
7. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.
8. The ratio of the speed of the driving member of a gear train to that of the driven member.
10. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
11. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.
16. The ability to do work.
18. A pear-shaped disk with an off-center pivot point, used to change rotating motion into reciprocating motion.
19. A threaded shaft used to convert rotary movement to linear movement.
21. The member of a pair of gears to which motion and power are transmitted by the other. The output gear.
23. The transmission of power between shafts by means of a belt connecting pulleys on the shafts.
25. Opposite in position, direction, order or effect.
