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






2. A push or pull on an object.






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






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






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






6. Work= force x distance






7. Stored energy






8. A way to measure stuff.






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






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






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






12. 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.






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






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






15. The distance between adjacent threads in a screw.






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






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






18. A twisting force.






19. A combo of several pulleys working together.






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






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






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






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






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






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






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






27. A back and forth movement.






28. Acts on a certain area.






29. Circular movement.






30. Movement in a straight line.






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






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






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






34. 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.


35. The ability to do work.






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






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






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






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






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






41. Measurement for work






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






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






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






45. The gear being turned buy the driver gear






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






47. 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.






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






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






50. The energy of motion.
