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 way to measure stuff.






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






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






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






5. A combo of several pulleys working together.






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






7. Acts on a certain area.






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






9. The results of the operation of any system.






10. The energy of motion.






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






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






13. Measurement for work






14. 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.






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






16. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






32. A machine used for raising or moving liquids.






33. Circular movement.






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






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






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






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






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






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






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






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






43. Movement in a straight line.






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






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






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






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






48. 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.


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






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