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






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






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






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






5. The distance between adjacent threads in a screw.






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






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






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






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






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






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






12. A push or pull on an object.






13. 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.






14. A combo of several pulleys working together.






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






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






17. The ability to do work.






18. A machine used for raising or moving liquids.






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






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






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






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






23. 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.


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






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






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






27. Measurement for work






28. The results of the operation of any system.






29. A back and forth movement.






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






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






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






34. Circular movement.






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






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






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






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






39. A twisting force.






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






41. Work= force x distance






42. Movement in a straight line.






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






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






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






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






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






48. The energy of motion.






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






50. Stored energy
