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. Opposite in position - direction - order or effect.






2. The ability to do work.






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






4. A twisting force.






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






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






7. Work= force x distance






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 energy of motion.






11. 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.






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






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






15. The gear being turned buy the driver gear






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






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






18. Measurement for work






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






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






21. Movement in a straight line.






22. 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.






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






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






25. A combo of several pulleys working together.






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






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






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






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






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






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






32. A way to measure stuff.






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






34. A push or pull on an object.






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






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






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






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






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






41. The distance between adjacent threads in a screw.






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






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






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






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






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






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






48. A machine used for raising or moving liquids.






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






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