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. 100khz






2. Elongation of grain flow in direction of rolling






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






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






5. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






6. Good wear - case hardening. ball bearings






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






8. Rubbers






9. 1/4 of the wavelength (higher better)






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






11. Better properties that would come from machining






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






13. Soft - ductile






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






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






16. Good toughness and fatigue. high strength structures






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






18. 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






19. 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






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






21. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






22. AC to DC






23. Difference/original






24. 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






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






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






27. High pressure

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






29. Vertical






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






31. 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






32. 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






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






34. Good high temp wear - tools






35. 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.






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






37. Produces; harder - stronger and less ductile product






38. Ma/vr x 100/1






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






40. Low pressure

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






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






43. 1GHZ






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






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






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






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






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






49. When upper die is dropped on bottom






50. Area load piston/area of effort piston
