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






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






3. Stored energy






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






5. 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.

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






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






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






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






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






24. A way to measure stuff.






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






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






27. The ability to do work.






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






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






30. 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.






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






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






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






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






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






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






37. Measurement for work






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






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






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






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






42. A twisting force.






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






44. A push or pull on an object.






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






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






47. 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.






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






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






50. Movement in a straight line.
