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






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 Fluorescent light is turned on to expose any left over - I.e in the cracks






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






4. 10MHZ






5. MA=VR






6. Hard - brittle






7. Area load piston/area of effort piston






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






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






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






11. 100GHZ+






12. 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






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






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






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






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






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






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






19. 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.






20. Hard - strong






21. Area parallel to force






22. Horizontal






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






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






25. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






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






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






28. Soft - ductile






29. Good wear - case hardening. ball bearings






30. Load/area






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. Resulting from exposure to damp environments and liquids.






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






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






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






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






37. Ma/vr x 100/1






38. 100khz






39. These have weaker secondary bonds which allow the stretching






40. Elongation of grain flow in direction of rolling






41. AC to DC






42. Usually used together - strengthening and toughness






43. Rubbers






44. High pressure

45. Vertical






46. Good high temp wear - tools






47. 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






48. 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






49. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






50. When upper die is dropped on bottom
