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. The results of the operation of any system.






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






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






4. Movement in a straight line.






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






6. Work= force x distance






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






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






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






10. A twisting force.






11. The distance between adjacent threads in a screw.






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






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






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






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






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






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






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






19. The gear being turned buy the driver gear






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






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






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






23. A machine used for raising or moving liquids.






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






25. 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.






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






27. A back and forth movement.






28. Measurement for work






29. 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.






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






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






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






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






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






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






36. Stored energy






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






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






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






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






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






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






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






44. A push or pull on an object.






45. The energy of motion.






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






47. A combo of several pulleys working together.






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






49. Circular movement.






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