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






2. 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.






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






4. The gear being turned buy the driver gear






5. A twisting force.






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






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






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






9. Acts on a certain area.






10. 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.






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






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






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






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






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






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






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






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






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






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






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






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






23. A machine used for raising or moving liquids.






24. Movement in a straight line.






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






26. The distance between adjacent threads in a screw.






27. A way to measure stuff.






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






29. Work= force x distance






30. A back and forth movement.






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






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






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






34. A push or pull on an object.






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






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






37. Measurement for work






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






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






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






41. Circular movement.






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






43. The ability to do work.






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






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






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






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






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






49. A combo of several pulleys working together.






50. Stored energy
