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. Hard - brittle






2. Area load piston/area of effort piston






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






4. Glass that is strengthened by introducing stress through rapid heating and cooling of the glass surfaces






5. AC to DC






6. Good high temp wear - tools






7. 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.






8. Difference/original






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






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






11. 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






12. Resulting from exposure to damp environments and liquids.






13. Hard - strong






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






15. 1%<X<2% carbon. more cementite - used for files






16. Area parallel to force






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






18. Low pressure


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






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






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






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






23. Load/area






24. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






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






27. 10MHZ






28. Vertical






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






30. 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






31. A method of transmitting signals by changing the frequency of a wave






32. Field winding parallel to armature winding. Bad for direct coupling






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






34. 100GHZ+






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






36. 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






37. MA=VR






38. Ma/vr






39. Good toughness and fatigue. high strength structures






40. Squeezing of the hot metal between two shaped dies excess is cut off






41. An orbit in which a satellite orbits Earth at the same rate as Earth rotates and thus stays over the same place all the time






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






43. Mass X gravity X height






44. Usually used together - strengthening and toughness






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






46. Ma/vr x 100/1






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






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






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






50. 100khz
