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






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






3. Work= force x distance






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






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






6. A twisting force.






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






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






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






10. Acts on a certain area.






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






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






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






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






15. 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.






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






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






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






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






20. 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.






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






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






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






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






25. A way to measure stuff.






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






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






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






29. A back and forth movement.






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






31. 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.






32. 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.






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. The ability to do work.






35. The results of the operation of any system.






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






37. Movement in a straight line.






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






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






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






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






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






43. The gear being turned buy the driver gear






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






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






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






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






48. A push or pull on an object.






49. Measurement for work






50. Stored energy
