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






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






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






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






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






6. The gear being turned buy the driver gear






7. 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.






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






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






10. 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.






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






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






13. Stored energy






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






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






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






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






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






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






20. Acts on a certain area.






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






22. Measurement for work






23. Movement in a straight line.






24. The ability to do work.






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






26. Work= force x distance






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






28. A back and forth movement.






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






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






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






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






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






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






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






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






39. The distance between adjacent threads in a screw.






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






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






42. The results of the operation of any system.






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






44. A twisting force.






45. A push or pull on an object.






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






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






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






49. 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.


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