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. 10MHZ






2. Better properties that would come from machining






3. Vertical






4. Soft - ductile






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






6. Ma/vr






7. Produces; harder - stronger and less ductile product






8. Rubbers






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






10. MA=VR






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






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






13. 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






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






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






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






17. Horizontal






18. 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.






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






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






21. Good toughness and fatigue. high strength structures






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






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






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






25. 1GHZ






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






27. A motor that is light - rugged and very reliable - runs on ac current and are more common in robotics. Can only run at a certain speed






28. Area parallel to force






29. 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






30. AC to DC






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






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






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






34. Hard - brittle






35. 100GHZ+






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






37. When upper die is dropped on bottom






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






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






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






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






42. 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






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






44. Load/area






45. 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






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






47. Low pressure

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






49. 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






50. High pressure
