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






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






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






4. 1/2Xmass X velocity X velocity






5. 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






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






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






8. Load/effort






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






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






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






12. Ma/vr






13. Produces; harder - stronger and less ductile product






14. High pressure

16. 100GHZ+






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






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






19. Resulting from exposure to damp environments and liquids.






20. Rubbers






21. Area load piston/area of effort piston






22. Good high temp wear - tools






23. 1GHZ






24. Elongation of grain flow in direction of rolling






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






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






27. 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






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






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






30. Vertical






31. Horizontal






32. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






33. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






34. MA=VR






35. Hard - brittle






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






37. Usually used together - strengthening and toughness






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






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






40. 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






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






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






43. Load/area






44. 1%<X<2% carbon. more cementite - used for files






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






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






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






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






49. Mass X gravity X height






50. When upper die is dropped on bottom
