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 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.






2. A back and forth movement.






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






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






5. A twisting force.






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






7. A push or pull on an object.






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






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






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






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






12. A machine used for raising or moving liquids.






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






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






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






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






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






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






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






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






21. 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.






22. 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.






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






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






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






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






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






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






29. The energy of motion.






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






31. Stored energy






32. A way to measure stuff.






33. Work= force x distance






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






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






36. Measurement for work






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






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






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






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






41. 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.






42. Movement in a straight line.






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






44. Acts on a certain area.






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






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






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






48. The gear being turned buy the driver gear






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






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