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






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






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






4. Good wear - case hardening. ball bearings






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






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






7. Hard - brittle






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






9. Resulting from exposure to damp environments and liquids.






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






11. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






12. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






13. Ma/vr x 100/1






14. Good high temp wear - tools






15. Area load piston/area of effort piston






16. Soft - ductile






17. Vertical






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






19. Horizontal






20. Better properties that would come from machining






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






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






23. 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






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






25. Mass X gravity X height






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






27. Hard - strong






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






29. 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






30. AC to DC






31. 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.






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






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






34. 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.






35. 100GHZ+






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






37. Elongation of grain flow in direction of rolling






38. Good toughness and fatigue. high strength structures






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






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






41. 1%<X<2% carbon. more cementite - used for files






42. High pressure

43. 1/2Xmass X velocity X velocity






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






45. Produces; harder - stronger and less ductile product






46. 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






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






48. 100khz






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






50. When upper die is dropped on bottom
