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. Work= force x distance






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






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






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






5. 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.






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






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






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






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






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






11. The ability to do work.






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






13. The energy of motion.






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






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






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






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






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






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






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






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






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






23. The gear being turned buy the driver gear






24. 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.






25. A push or pull on an object.






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






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






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






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






30. A back and forth movement.






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






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






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






34. 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.


35. A machine used for raising or moving liquids.






36. 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.






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






38. The results of the operation of any system.






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






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






41. Circular movement.






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






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






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






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






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






47. Measurement for work






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






49. 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.






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