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






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






3. 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






4. 0.15%<X<0.3% carbon. more pearlite - most common steel. weldable up to 0.2 used in structures






5. 100GHZ+






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






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






8. 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






9. 1/4 of the wavelength (higher better)






10. 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






11. 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






12. 1GHZ






13. Vertical






14. Elongation of grain flow in direction of rolling






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






16. 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






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






18. Good wear - case hardening. ball bearings






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






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






21. 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






22. AC to DC






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






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






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






26. Area load piston/area of effort piston






27. Hard - strong






28. 1/2Xmass X velocity X velocity






29. Hard - brittle






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






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






32. Resulting from exposure to damp environments and liquids.






33. Ma/vr x 100/1






34. Usually used together - strengthening and toughness






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






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






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






38. High pressure

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






40. Soft - ductile






41. Ma/vr






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






43. Rubbers






44. Load/area






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






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






47. Produces; harder - stronger and less ductile product






48. 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






49. MA=VR






50. 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
