Mechanical Systems 2

Subject : engineering
Instructions:
  • 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.

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






16. Work= force x distance






17. Movement in a straight line.






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






19. A combo of several pulleys working together.






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






21. Acts on a certain area.






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






23. The gear being turned buy the driver gear






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






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






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






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






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






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






30. 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.

33. The ability to do work.






34. 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.






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






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






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






38. The energy of motion.






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






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






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






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






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






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






45. The distance between adjacent threads in a screw.






46. 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.






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






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






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






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