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






2. Measurement for work






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






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






5. The distance between adjacent threads in a screw.






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






7. A combo of several pulleys working together.






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






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






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






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






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






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. The force acting perpendicular to a certain surface area.






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






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






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






18. A back and forth movement.






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






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






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






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






23. The energy of motion.






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






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






26. 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.






27. 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.






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






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






30. The results of the operation of any system.






31. A twisting force.






32. A push or pull on an object.






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






34. The ability to do work.






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






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






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






38. Movement in a straight line.






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






40. 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.






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






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






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






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






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






46. A machine used for raising or moving liquids.






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






48. A way to measure stuff.






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






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