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.

32. The difficulties we must overcome






33. When designing a solution to a problem - a problem solver should always






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






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






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






37. The force applied to a lever






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






39. The generation of ideas for solutions






40. The process of how solutions to problems are developed is






41. The force (push or pull) used to do work






42. A lever in which the fulcrum is between the effort and the load






43. Provides direction for the work of the designer






44. If you generate alternative solutions and begin to build your best solution - but you have problems building your design - what should you do?






45. Changes and improvements made to products already invented are
