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 push or pull on an object.






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






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






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






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






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






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






11. The gear being turned buy the driver gear






12. Circular movement.






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






14. Measurement for work






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






16. Stored energy






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






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






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






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






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






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






23. The distance between adjacent threads in a screw.






24. 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.






25. 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.


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






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






28. Work= force x distance






29. The ability to do work.






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






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






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






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






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






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






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






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






38. A twisting force.






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






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






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






42. A way to measure stuff.






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






44. Movement in a straight line.






45. 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.






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






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






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






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






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