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 machine used for raising or moving liquids.






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






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






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






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






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






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






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






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






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






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






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






13. The results of the operation of any system.






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






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






16. The ability to do work.






17. A combo of several pulleys working together.






18. The gear being turned buy the driver gear






19. Measurement for work






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






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






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






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






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






25. 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.






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






27. 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.






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






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






30. 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.






31. A way to measure stuff.






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






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






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






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






36. The energy of motion.






37. A push or pull on an object.






38. Acts on a certain area.






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






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






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






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






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






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






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






46. Circular movement.






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






48. The distance between adjacent threads in a screw.






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






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