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






2. Elongation of grain flow in direction of rolling






3. 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






4. Soft - ductile






5. 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






6. 1/2Xmass X velocity X velocity






7. 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






8. Better properties that would come from machining






9. Vertical






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. Difference/original






13. Ma/vr






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






15. Usually used together - strengthening and toughness






16. 1%<X<2% carbon. more cementite - used for files






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






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






19. Load/area






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






21. 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.






22. When upper die is dropped on bottom






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






24. High pressure

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






26. Horizontal






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






28. Mass X gravity X height






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






30. Good wear - case hardening. ball bearings






31. 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






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






33. These have weaker secondary bonds which allow the stretching






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






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






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






37. 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






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






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






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






41. 1GHZ






42. Low pressure

43. Resulting from exposure to damp environments and liquids.






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






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






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






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






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






49. Load/effort






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