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






2. 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.






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






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






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






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






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






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






9. The distance between adjacent threads in a screw.






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






11. Work= force x distance






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. Circular movement.






14. A machine used for raising or moving liquids.






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






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






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






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






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






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






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






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






23. Stored energy






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






25. Measurement for work






26. 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.






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






28. A push or pull on an object.






29. The results of the operation of any system.






30. The ability to do work.






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






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






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






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






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






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






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






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






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






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






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






42. The gear being turned buy the driver gear






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






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






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






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






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






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






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






50. The energy of motion.
