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






2. Measurement for work






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






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






5. Work= force x distance






6. 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.






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






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






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






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






11. Stored energy






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






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






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






15. A back and forth movement.






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






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






18. 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.






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






20. The results of the operation of any system.






21. The ability to do work.






22. A secondary or subordinate system that is part if a larger 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 distance in a strait line from the center of a circle to the circle circumference






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






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






27. A twisting force.






28. A machine used for raising or moving liquids.






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






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






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






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






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






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






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






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






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






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






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






40. Circular movement.






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






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






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






44. 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.


45. Acts on a certain area.






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






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






48. The distance between adjacent threads in a screw.






49. A combo of several pulleys working together.






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