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

2. Circular movement.

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

4. 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.

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

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

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

8. The energy of motion.

9. 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.

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

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

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

13. The results of the operation of any system.

14. Acts on a certain area.

15. A way to measure stuff.

16. Work= force x distance

17. 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.

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

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

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

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

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

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

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

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

27. A twisting force.

28. Stored energy

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

30. Measurement for work

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

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

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

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

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

36. A back and forth movement.

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

38. A machine used for raising or moving liquids.

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

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

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

42. A pivot pin near the outside edge of a wheel or disk that changes reciprocating motion into rotary 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 push or pull on an object.

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

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

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

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

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

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