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.

15. Force - work done - power - mechanical efficiency






16. Reflex angle






17. Combines easily with many other elements - improves atmospheric corrosion resistance - increases strength - amounts of 0.15-0.25%






18. Pre- construction - shows graphically the mechanical design engineer's work - during construction - proper location - reference to all equipment - after construction - training reference anddetails of process - utility and electrical systems






19. A triangle with two equal sides






20. One is the trigonometric value of...

29. coefficient of expansion






30. Is the required to change a unit mass from a gas to liquid or liquid to a gas






31. PV=nRT - Boyle's law and Charle's law combined






32. Resists oxidation - high strength at high temperatures - increases hardness and abrasion resistance without increasing brittleness - increases response to heat treatment - increases depth of hardness penetration - at 12% chromium steel with not tarni






33. Potential energy (Ep)






34. Is 'the equivalent mass of water that would require the same amount of heat transfer as the substance - to produce the same temp. change
