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. Good toughness and fatigue. high strength structures






2. 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






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






4. Better properties that would come from machining






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






6. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






7. 1/4 of the wavelength (higher better)






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






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






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






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






12. Hard - brittle






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






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






15. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






17. 1GHZ






18. 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






19. Area parallel to force






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






21. 1%<X<2% carbon. more cementite - used for files






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






23. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






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






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






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






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






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






29. 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






30. Ma/vr






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






32. 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






33. Horizontal






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






35. Area load piston/area of effort piston






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






37. 1/2Xmass X velocity X velocity






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






39. Rubbers






40. Good high temp wear - tools






41. Produces; harder - stronger and less ductile product






42. 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






43. 100GHZ+






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






45. Low pressure

46. 100khz






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






48. When upper die is dropped on bottom






49. 10MHZ






50. Good wear - case hardening. ball bearings
