Principles Of Engineering

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. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






2. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

20. The tank that holds the fluid in a hydraulic system.






21. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






22. A valve that allows flow in one direction but prevents flow in the opposite direction.






23. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O
