Introduction To Engineering - 7

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.

19. A lever in which the fulcrum is at one end - and the effort is at the other end






20. The generation of ideas for solutions






21. Models that function and look like the finished product but are usually hand- built






22. Two wheels that intermest at an angle to change the direction of rotation - also altering speed and force if necessary






23. A system of pulleys that consists of one rope wound around two separate sets of pulley - each of which is free to rotate independently on the same axle






24. The study of how human beings best interact with technology






25. A lever in which the fulcrum is at one end - and the load is at the other end






26. Provides a framework for design and problem solving work






27. The generation of ideas for solutions by a group is known as
