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






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






3. Stored energy






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






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






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






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






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






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






10. A back and forth movement.






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






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






13. The ability to do work.






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






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






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






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






18. Work= force x distance






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






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






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






22. The gear being turned buy the driver gear






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






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






25. A machine used for raising or moving liquids.






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






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






28. Movement in a straight line.






29. The distance between adjacent threads in a screw.






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






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






32. The results of the operation of any system.






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






34. A way to measure stuff.






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






36. 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.






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






38. The energy of motion.






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






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






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






42. Circular movement.






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






44. A push or pull on an object.






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






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






47. 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.






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






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






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