Subject : engineering
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A pulley supported by attachment to something that does not move - such as a ceiling - wall - or tree.

2. The that has a handle because of a motoe or person turning it.

3. A secondary or subordinate system that is part if a larger system.

4. A twisting force.

5. The quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

6. A law stating that when pressuer is exerted on on part of a fluid - the same pressure is transmitted unchanged to all parts of the fluid - no matter what the shape of the container holding fluid. EX: water balloon.

7. The transmission of power between shafts by means of a belt connecting pulleys on the shafts.

8. The application of force that moves an object a certain distance.

9. Something put into a system - such as resources - in order to achieve a result.

10. A system having a boundary that separates it from it surroundings.

11. The gear which transmits power and motion to the rest of the system. The input gear.

12. The distance in a strait line from the center of a circle to the circle circumference

13. A way to measure stuff.

14. A wheel with a grooved rim to guide a rope or chain that runs along the groove; used to transmit or change direction of force.

15. The work done on a machine as the input force acts through the input distance

16. Circular movement.

17. A lever in which the effort is applied between the fulcrum and the load.

18. Movement in a straight line.

19. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.

20. Measurement for work

21. Work= force x distance

22. A gear between the driver and the driven gear used to change rotational direction.

23. The gear being turned buy the driver gear

24. A system in which a gas - such as air - transmits a force exerted on gas in an enclosed space.

25. The ability to do work.

26. Opposite in position - direction - order or effect.

27. A mechanical arrangement consisting of a toothed wheel driven by a short revolving cylinder bearing a screw thread.

28. A mechanical system that uses a liquid under pressure in a close system to raise heavy objects.

29. The part of a machine which contains two or more pieces arranged so that the motion of one compels the motion of the others.

30. A combination of fixed and movable pulleys - may be used to list very heavy or awkward loads.

31. A lever in which the fulcrum is between the effort and load.

32. A back and forth movement.

33. Energy is transferred from one plan to another - and no energy is changed or converted.

34. The results of the operation of any system.

35. A combination of two or more gears used to transmit motion between two rotating shafts or between a shaft and a slide.

36. A machine used for raising or moving liquids.

37. The point of the lever that does not move.

38. A device used to regulate the flow of a liquid in a hydraulic system.

39. The energy of motion.

40. A swing back and forth at a regular rate.

41. The science of designing gone or work environments that best suit the human body in it various dimensions.

42. A toothed wheel that works with others to alter the relation between the speed of an engine and the speed of the driven parts.

43. A joint that allows connected shafts to spin freely while permitting a change in direction.

44. A machine consisting of two turning objects attached to each other at thier centers. One object to turn

45. The ratio of the force produced by a machine or system (the load) to the force applied to the machine or system.

46. A combo of several pulleys working together.

47. The member of a pair of gears to which motion and power are transmitted by the other. The output gear.

48. The distance between adjacent threads in a screw.

49. A pear- shaped disk with an off- center pivot point - used to change rotating motion into reciprocating motion.

50. A push or pull on an object.
