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. Measurement for work






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






3. The results of the operation of any system.






4. 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.






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






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






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






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






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






10. The energy of motion.






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






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






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






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






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






16. Circular movement.






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






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






19. Acts on a certain area.






20. 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.






21. 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.






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






23. A combo of several pulleys working together.






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






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






26. The gear being turned buy the driver gear






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






28. A rotating gear that meshes with a bar that has gear teeth along its length. Changes rotating motion into linear motion.






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






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






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






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






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






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






35. A twisting force.






36. Work= force x distance






37. A back and forth movement.






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






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






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






41. A push or pull on an object.






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






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






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






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






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






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






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






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






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