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






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






3. Measurement for work






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






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






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






7. Stored energy






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






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






10. Circular movement.






11. 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.

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






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






22. 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.






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






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






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






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






27. A push or pull on an object.






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






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






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






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






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






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






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






35. A twisting force.






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






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






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






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






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






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






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






43. The gear being turned buy the driver gear






44. The energy of motion.






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






46. A back and forth movement.






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






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






49. Work= force x distance






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