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 continuous band of tough flexible material used to transmit motion and power within a pulley system.






2. The rate at which work is performed or energy is expended






3. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






4. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






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