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






2. A solid state component made from three layers of semiconductor material that can amplify the strenght of an electric signal or act as an electronic switch






3. Soft - ductile






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






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






6. A strong hard building material composed of sand and gravel and cement and water






7. Load/effort






8. Horizontal






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






10. Based on the principle that magnetic materials will have distorted magnetic fields in the vicinity of material defects






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






12. Hard - strong






13. Used where scarifical anodes cannot supply enough protection - offshore oil rigs - buried pipes - big things. protection is provided by connecting a rectifier to provide a direct current source between the anode and the metal being protected.






14. Ma/vr






15. When upper die is dropped on bottom






16. Rubbers






17. Vertical






18. A cable made of optical fibers that can transmit large amounts of information at the speed of light






19. Forming of metal by compressive force above recrystallization point.






20. Low pressure

21. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






22. 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






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






24. The greater the sulphur the harder the rubber to stretch






25. Better properties that would come from machining






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






27. Ma/vr x 100/1






28. Good toughness and fatigue. high strength structures






29. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






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






32. Resulting from exposure to damp environments and liquids.






33. Area parallel to force






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






35. 1%<X<2% carbon. more cementite - used for files






36. Difference/original






37. Can be reflected of the ionosphere - 3 to 30 megahertz






38. Majority silicon X>1.5% for graphite. Graphite in flakes that cause stress points






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






40. 100khz






41. 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.






42. Solid at room temp - weak secondary bonds. can be reheated multiply times.






43. Elongation of grain flow in direction of rolling






44. Usually used together - strengthening and toughness






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






46. Hard - brittle






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






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






49. High pressure

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