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 back and forth movement.






2. 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.






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






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






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






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






8. Circular movement.






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






10. A combo of several pulleys working together.






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






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






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






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






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






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






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






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






19. The ability to do work.






20. The results of the operation of any system.






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






22. A way to measure stuff.






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






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






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






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






27. The gear being turned buy the driver gear






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






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






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






31. Stored energy






32. The distance between adjacent threads in a screw.






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






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






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






36. A twisting force.






37. 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.






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






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






40. Movement in a straight line.






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






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






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






44. 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.






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






46. 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.






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






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






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






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