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. Elongation of grain flow in direction of rolling






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






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






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






5. Hard - strong






6. Low pressure

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






8. 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






9. 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






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






11. High pressure

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






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






14. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






15. 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.






16. Vertical






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






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






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






20. Mass X gravity X height






21. Ma/vr






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






23. AC to DC






24. Good toughness and fatigue. high strength structures






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






26. Rubbers






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. 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






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






30. Usually used together - strengthening and toughness






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






32. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






34. Good high temp wear - tools






35. 1%<X<2% carbon. more cementite - used for files






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






37. Area load piston/area of effort piston






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






39. Produces; harder - stronger and less ductile product






40. Good wear - case hardening. ball bearings






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






42. Resulting from exposure to damp environments and liquids.






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






44. Load/area






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






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






47. 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






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






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