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. 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.






2. High pressure

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






4. Area parallel to force






5. When upper die is dropped on bottom






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






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






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






9. Rubbers






10. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






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






12. Ma/vr x 100/1






13. Resulting from exposure to damp environments and liquids.






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






15. Ma/vr






16. 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






17. MA=VR






18. Good wear - case hardening. ball bearings






19. Area load piston/area of effort piston






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






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






22. 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






23. 10MHZ






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






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






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






27. Soft - ductile






28. Load/area






29. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






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






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






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






33. Vertical






34. Difference/original






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






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






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






38. These have weaker secondary bonds which allow the stretching






39. AC to DC






40. Usually used together - strengthening and toughness






41. Low pressure

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






43. 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






44. 1GHZ






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






46. 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






47. Produces; harder - stronger and less ductile product






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. The greater the sulphur the harder the rubber to stretch






50. Good toughness and fatigue. high strength structures
