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.
1. A back and forth movement.






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






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






4. A push or pull on an object.






5. Acts on a certain area.






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

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






11. A way to measure stuff.






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






13. A combo of several pulleys working together.






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






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






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






17. 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.






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






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






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






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






22. 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.






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






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






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






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






27. Work= force x distance






28. A twisting force.






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






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






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






32. The energy of motion.






33. Circular movement.






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






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






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






37. A machine used for raising or moving liquids.






38. The gear being turned buy the driver gear






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






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






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






42. The ability to do work.






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






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






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






46. Movement in a straight line.






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






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






49. The distance between adjacent threads in a screw.






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