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

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

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

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

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

6. 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.

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

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

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

10. Stored energy

11. A machine used for raising or moving liquids.

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

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

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

15. A way to measure stuff.

16. A twisting force.

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

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

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

20. A combo of several pulleys working together.

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

22. Movement in a straight line.

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

24. The gear being turned buy the driver gear

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

26. Work= force x distance

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

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

29. 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.

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

31. A push or pull on an object.

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

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

34. The results of the operation of any system.

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

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

37. The ability to do work.

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

39. Circular movement.

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

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

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

43. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary motion.

44. Measurement for work

45. The realtioship between the speed of rotation of a smaller gear and a larger gear = number of driven gear teeth / Number of following gear teeth.

46. Acts on a certain area.

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

48. The ratio of the speed of the driving member of a gear train to that of the driven member.

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

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