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






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






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






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






5. A machine used for raising or moving liquids.






6. 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.

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






8. 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.






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






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






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






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






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






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






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






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






17. A way to measure stuff.






18. Work= force x distance






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






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






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






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






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






24. A twisting force.






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






26. The gear being turned buy the driver gear






27. A back and forth movement.






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






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






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






31. Measurement for work






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






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






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






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






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






37. A combo of several pulleys working together.






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






39. The distance between adjacent threads in a screw.






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






41. The ability to do work.






42. Stored energy






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






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






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






46. A push or pull on an object.






47. The energy of motion.






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






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






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