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






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






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






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






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






6. A way to measure stuff.






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






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






9. A twisting force.






10. A back and forth movement.






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






12. The gear being turned buy the driver gear






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






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






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






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






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






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






19. Movement in a straight line.






20. A combo of several pulleys working together.






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






22. Circular movement.






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






24. Stored energy






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






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






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






28. The ability to do work.






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






30. The distance between adjacent threads in a screw.






31. 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.






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






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






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






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






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






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






38. Work= force x distance






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






40. The energy of motion.






41. 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.






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






43. The results of the operation of any system.






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






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






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






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






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






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






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