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

2. A machine used for raising or moving liquids.

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

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

5. 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.

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

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

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

9. The energy of motion.

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

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

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

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

14. A combo of several pulleys working together.

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

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

17. A back and forth movement.

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

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

20. A twisting force.

21. The ability to do work.

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

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

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

25. A way to measure stuff.

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

27. 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.

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

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

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

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

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

33. Stored energy

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

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

36. 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.

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

38. A push or pull on an object.

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

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

42. The distance between adjacent threads in a screw.

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

44. 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.

45. Work= force x distance

46. The gear being turned buy the driver gear

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

48. Movement in a straight line.

49. 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.

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