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 threaded shaft used to convert rotary movement to linear movement.






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






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






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






5. Measurement for work






6. A way to measure stuff.






7. A push or pull on an object.






8. A combo of several pulleys working together.






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






10. 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.






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






12. The gear being turned buy the driver gear






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






14. 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.






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






16. A back and forth movement.






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






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






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






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






21. Acts on a certain area.






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






23. Stored energy






24. 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.






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






26. The energy of motion.






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






28. 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.


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






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






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






32. The distance between adjacent threads in a screw.






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






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






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






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






37. The results of the operation of any system.






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






39. Work= force x distance






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






41. Circular movement.






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






43. Movement in a straight line.






44. The ability to do work.






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






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






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






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






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






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