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. MA=VR






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






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






4. 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






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






6. Produces; harder - stronger and less ductile product






7. 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






8. Area parallel to force






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






10. Vertical






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






12. Elongation of grain flow in direction of rolling






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






14. 1GHZ






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






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






17. 10MHZ






18. Usually used together - strengthening and toughness






19. 100khz






20. 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.






21. 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






22. These have weaker secondary bonds which allow the stretching






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






24. 100GHZ+






25. 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






26. Load/effort






27. Good wear - case hardening. ball bearings






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






29. Ma/vr






30. High pressure

31. Area load piston/area of effort piston






32. 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






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






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






35. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






36. When upper die is dropped on bottom






37. 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






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






39. Horizontal






40. 1%<X<2% carbon. more cementite - used for files






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






42. Difference/original






43. 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






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






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






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






47. Hard - strong






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






49. 1/2Xmass X velocity X velocity






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