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

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

3. Stored energy

4. 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.

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

6. Circular movement.

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

8. A machine consisting of a bar that is free to rotate around a fixed point - changing the amount of force that must be exerted to move an object.

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

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

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

12. A combo of several pulleys working together.

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

14. A small cogwheel that engages or is engaged by a larger cogwheel.

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

16. Measurement for work

17. The gear being turned buy the driver gear

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

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

20. A back and forth movement.

21. Work= force x distance

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

23. A twisting force.

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

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

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

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

28. 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.

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

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

31. The results of the operation of any system.

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

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

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

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

36. A push or pull on an object.

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

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

39. 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.

40. 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.

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

42. The energy of motion.

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

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

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

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

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

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

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

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