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. 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






2. These have weaker secondary bonds which allow the stretching






3. Resulting from exposure to damp environments and liquids.






4. Good high temp wear - tools






5. 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.






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






7. Mass X gravity X height






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






9. 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






10. 1GHZ






11. When upper die is dropped on bottom






12. Load/area






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






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






15. Area load piston/area of effort piston






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






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






18. Elongation of grain flow in direction of rolling






19. 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






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






21. High pressure

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






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






24. 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






25. Ma/vr x 100/1






26. MA=VR






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






28. Rubbers






29. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






30. Horizontal






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






32. Produces; harder - stronger and less ductile product






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






34. Low pressure

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






36. 100GHZ+






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






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






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






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






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






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






43. Involves heating the piece above Red heat and then letting it cool in air. causes smaller grains






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






45. AC to DC






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






47. 1%<X<2% carbon. more cementite - used for files






48. The greater the sulphur the harder the rubber to stretch






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






50. Difference/original
