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. Circular movement.






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






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






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






6. A push or pull on an object.






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






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






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






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






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






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






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






14. Acts on a certain area.






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






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






17. Measurement for work






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






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






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






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






22. Movement in a straight line.






23. 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.






24. A way to measure stuff.






25. A machine used for raising or moving liquids.






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






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






28. A twisting force.






29. 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.






30. A back and forth movement.






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






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






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






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






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






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






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






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






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






40. Stored energy






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






42. 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.






43. The results of the operation of any system.






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






45. The gear being turned buy the driver gear






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






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






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






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






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