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 back and forth movement.






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






3. A way to measure stuff.






4. The gear being turned buy the driver gear






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






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






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 point of the lever that does not move.






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






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






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






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






13. A push or pull on an object.






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






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






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






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






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






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






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






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






22. The results of the operation of any system.






23. 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.






24. A twisting force.






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






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






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






28. The ability to do work.






29. 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.






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






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






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






33. Circular movement.






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






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






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






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






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






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






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






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






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






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






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






45. 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.






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






47. Movement in a straight line.






48. A combo of several pulleys working together.






49. A machine used for raising or moving liquids.






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