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.

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






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






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






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






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






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