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. Elongation of grain flow in direction of rolling






2. Rubbers






3. Controlled cooling after heating metal to attain a degree of hardness. removes internal stresses






4. Usually used together - strengthening and toughness






5. A device that converts the AC inside a DC generator to a DC output or converts a DC supply to an AC inside a DC motor.keeping the armature rotating






6. Load/area






7. Involves heating the piece above Red heat and then letting it cool in air. causes smaller grains






8. Dye is sprayed onto a surface - with excess being wiped away - meaning any left on the piece would be in cracks that exist in it. A developer is then added to it to expose any left over - I.e in the cracks






9. Results from the changing anode and cathode regions over the entire surface






10. Vertical






11. Maximum bending moments X distance to natural axis/ second moment of area






12. Area parallel to force






13. Horizontal






14. 10MHZ






15. Can only be softened once - bonded strongly - generally stronger that thermoplastics. stronger secondary bonds






16. AC to DC






17. Ma/vr






18. Good wear - case hardening. ball bearings






19. 1%<X<2% carbon. more cementite - used for files






20. High pressure

21. Us a metal that is more reactive. It is connect to another metal and corrodes instead of the other metal. the Anode is replaced periodically






22. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






23. Difference/original






24. Glass made with plates of plastic or resin or other material between two sheets of glass to prevent shattering






25. When upper die is dropped on bottom






26. A flexible communications cable that contains pairs of insulated copper wires that are twisted together for reduction of EMI and RFI and covered with an outer insulating jacket.






27. Supply current to the rotating commutator from an external source






28. Softening a material such as metal by controlled heating and cooling. This makes the metal less brittle and more easily adaptable. Soaking till austenite then cooling slowly. large grains






29. X<1% silicon no graphite - has carbon/carbide. very brittle






30. 1/2Xmass X velocity X velocity






31. Mass X gravity X height






32. Soft - ductile






33. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






34. 100khz






35. Small amounts of magnesium to make spheres instead of flakes. thus no stress concentrations






36. The quantity of information that can be transmitted through a communication medium in a given amount of time.






37. Resulting from combined effect of stresses set up within the metal






38. Soaked cast iron at 870c for long time then cooled slow






39. Degradation of a signal as it travels over a cable. Attenuation increased with higher frequencies






40. Better properties that would come from machining






41. Being forced - under pressure - through a hole like toothpaste. either hot or cold






42. Ma/vr x 100/1






43. MA=VR






44. Allows for another signal to be sent along the carrier signal






45. A method of transmitting signals by changing the amplitude of a waves






46. Use of xrays passed through the material to make a visual record of internal structures on specially sensitized film






47. 100GHZ+






48. Steel reinforcing rusts - rust has a greater volume concrete then breaks of as a result.






49. 1/4 of the wavelength (higher better)






50. Dye is sprayed onto a surface - with excess being wiped away - meaning any left on the piece would be in cracks that exist in it. A Fluorescent light is turned on to expose any left over - I.e in the cracks
