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






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






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






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






5. 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.

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






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






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






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






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






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






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






17. Work= force x distance






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






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






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






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






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






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






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






25. Acts on a certain area.






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






27. The energy of motion.






28. A twisting force.






29. A push or pull on an object.






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






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






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






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






34. The distance between adjacent threads in a screw.






35. Stored energy






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






37. 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.






38. 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.






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






40. A way to measure stuff.






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






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






43. Measurement for work






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






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






46. Circular movement.






47. 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.






48. A machine used for raising or moving liquids.






49. Movement in a straight line.






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