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. Mass X gravity X height






2. Load/effort






3. 100khz






4. 1/2Xmass X velocity X velocity






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






6. 0.6%<X<1% carbon. almost entirely pearlite with cementite x>0.8% for high strength and wear






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






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






9. Hard - strong






10. MA=VR






11. Soft - ductile






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






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






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






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






16. Ma/vr x 100/1






17. Usually used together - strengthening and toughness






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






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






20. Ma/vr






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






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






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






24. 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






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






26. 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






27. Good wear - case hardening. ball bearings






28. These have weaker secondary bonds which allow the stretching






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






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






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






32. 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.






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






34. Area load piston/area of effort piston






35. 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






36. Rubbers






37. 1/4 of the wavelength (higher better)






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






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






40. High pressure

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






42. Resulting from exposure to damp environments and liquids.






43. Good toughness and fatigue. high strength structures






44. When upper die is dropped on bottom






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






46. Area parallel to force






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






48. 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






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






50. AC to DC
