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.
1. 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.






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






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






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

12. A back and forth movement.






13. A way to measure stuff.






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






15. Circular movement.






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






17. Measurement for work






18. 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.






19. A push or pull on an object.






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






21. The gear being turned buy the driver gear






22. The distance between adjacent threads in a screw.






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






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






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






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






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






28. A gear with teeth that fits into the links of a chain.






29. A combo of several pulleys working together.






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






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






32. The ability to do work.






33. Movement in a straight line.






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






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






36. Stored energy






37. 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.

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






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






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






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






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






43. Work= force x distance






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






45. Acts on a certain area.






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






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






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






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






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