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






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






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






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






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






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






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






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






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






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






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






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






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






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






15. A way to measure stuff.






16. Circular movement.






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






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






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






20. 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.

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






24. 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.






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






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






27. 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.






28. Work= force x distance






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






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






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






32. The gear being turned buy the driver gear






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






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






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






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






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






38. A machine used for raising or moving liquids.






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






40. Movement in a straight line.






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






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






43. A push or pull on an object.






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






45. The energy of motion.






46. A back and forth movement.






47. A twisting force.






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






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






50. A combo of several pulleys working together.
