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 threaded shaft used to convert rotary movement to linear movement.






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






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






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






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






6. A way to measure stuff.






7. A push or pull on an object.






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






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






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






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






12. A back and forth movement.






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






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






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






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






17. The distance between adjacent threads in a screw.






18. Measurement for work






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






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






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






22. 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.






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






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






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






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






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






28. The gear being turned buy the driver gear






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






30. A combo of several pulleys working together.






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






32. A machine used for raising or moving liquids.






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






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






35. Circular movement.






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






37. The energy of motion.






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






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






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






41. Work= force x distance






42. 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.






43. Stored energy






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






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






46. 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.






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






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






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






50. Movement in a straight line.
