Engineering Studies

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. Between 2000-35 -700km above the earth's surface.






2. Hard - strong






3. 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






4. Low pressure

5. Occurs when the metal is hammered by a vertically moving tool onto a stationary tool






6. An orbit less than 1 -500 km. above the Earth's surface.






7. 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






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. 100GHZ+






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






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






12. Difference/original






13. 1GHZ






14. Resulting from exposure to damp environments and liquids.






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






16. Horizontal






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






18. When upper die is dropped on bottom






19. Soft - ductile






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






21. 10MHZ






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






23. Produces; harder - stronger and less ductile product






24. Elongation of grain flow in direction of rolling






25. Ma/vr






26. 1%<X<2% carbon. more cementite - used for files






27. 1/4 of the wavelength (higher better)






28. High pressure

29. Area parallel to force






30. Sound waves sent through a material - much like sonar. Internal defects appear because they use more energy to go through it.






31. Usually used together - strengthening and toughness






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






33. Makes brittle by heating and then cooling quickly - less flexible. Red Heat then quenching






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






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






36. Load/area






37. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






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






40. x<0.15% carbon. ferrite. good for cold working - rolling sheets






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






42. Area load piston/area of effort piston






43. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






44. These have weaker secondary bonds which allow the stretching






45. Mass X gravity X height






46. Vertical






47. Good toughness and fatigue. high strength structures






48. Hard - brittle






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






50. Resulting from exposure to oxygen in the atmosphere - chemical fumes - steam - flue gas. creates a layer of metal oxide.
