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 system having a boundary that separates it from it surroundings.






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






3. Measurement for work






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






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






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






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






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






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






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






11. The distance between adjacent threads in a screw.






12. The energy of motion.






13. The ability to do work.






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






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






16. Work= force x distance






17. Circular movement.






18. The results of the operation of any system.






19. 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.






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






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






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






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






24. Stored energy






25. The gear being turned buy the driver gear






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






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






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






29. 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.






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






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






32. A back and forth movement.






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






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






35. The ratio of the useful work or energy provided by a machine or system with the actual work or energy supplied to the machine or system.






36. A common workplace disorder causing numbness and pain in the thumb and first three finger.






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






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






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






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






41. A machine used for raising or moving liquids.






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






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






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






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






46. Movement in a straight line.






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






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






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






50. A combo of several pulleys working together.
