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 force acting perpendicular to a certain surface area.






2. A machine used for raising or moving liquids.






3. 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.






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






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






6. Stored energy






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






8. 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.






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






10. Measurement for work






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






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






13. A push or pull on an object.






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






15. 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.






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






17. Work= force x distance






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






19. Acts on a certain area.






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






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






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






23. The gear being turned buy the driver gear






24. The ability to do work.






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






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






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






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






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






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






31. A combo of several pulleys working together.






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






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






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






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






36. A back and forth movement.






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






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






39. The results of the operation of any system.






40. The distance between adjacent threads in a screw.






41. The energy of motion.






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






43. Circular movement.






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






45. 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.






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






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






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






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






50. A way to measure stuff.
