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 machine used for raising or moving liquids.

2. A common workplace disorder causing numbness and pain in the thumb and first three finger.

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

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

5. A pulley supported by attachment to something that does not move - such as a ceiling - wall - or tree.

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

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

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

9. A push or pull on an object.

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

11. Stored energy

12. The ratio of the useful work or energy provided by a machine or system with the actual work or energy supplied to the machine or system.

13. The energy of motion.

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

15. The results of the operation of any system.

16. The ability to do work.

17. The distance between adjacent threads in a screw.

18. 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.

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

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

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

22. The weight of an object that is is moved or lifted by a machine - or resistance to movement that a machine must overcome

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

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

25. Acts on a certain area.

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

27. 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.

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

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

30. Work= force x distance

31. A rotating wheel- like device with teeth around the rim.

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

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

34. The work done by a machine as the output force acts through the output distance

35. One of a pair of gears used to connect two shafts whose axes intersect.

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

37. A combo of several pulleys working together.

38. The force acting perpendicular to a certain surface area.

39. Circular movement.

40. A threaded shaft used to convert rotary movement to linear movement.

41. A machine consisting of a small cylinder - a crank or handle - on a cable. Winch can be used to lift or pull things

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

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

44. A gear with teeth that fits into the links of a chain.

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

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

47. A back and forth movement.

48. Movement in a straight line.

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

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