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. The greater the sulphur the harder the rubber to stretch






2. Ma/vr x 100/1






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






4. Good high temp wear - tools






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






6. Area load piston/area of effort piston






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






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






9. Soft - ductile






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






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






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






13. Rubbers






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






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






16. Load/effort






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






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






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






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






21. 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






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






23. Low pressure

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






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






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






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. High pressure

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






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






31. 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.






32. 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






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






34. 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






35. 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






36. Usually used together - strengthening and toughness






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






38. Hard - brittle






39. Used where scarifical anodes cannot supply enough protection - offshore oil rigs - buried pipes - big things. protection is provided by connecting a rectifier to provide a direct current source between the anode and the metal being protected.






40. Elongation of grain flow in direction of rolling






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






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






43. Produces; harder - stronger and less ductile product






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






45. Area parallel to force






46. 1%<X<2% carbon. more cementite - used for files






47. 0.3%<X<0.6% carbon. mostly pear- lite - heat treatable. 0.4 used in axles






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






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