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 swing back and forth at a regular rate.






2. A twisting force.






3. Work= force x distance






4. 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.






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






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






7. The energy of motion.






8. The distance between adjacent threads in a screw.






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






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






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






12. 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.






13. The ability to do work.






14. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






33. Acts on a certain area.






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






35. Circular movement.






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






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






38. Measurement for work






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






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






41. Stored energy






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






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






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






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






46. A back and forth movement.






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






48. A push or pull on an object.






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






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