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






2. The difficulties we must overcome

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






7. When a machine multiplies the effort being used






8. 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






9. More than one pulley working together






10. Come in a variety of sizes with their teeth straight or curved and inclined at a variety of angles






11. A wheel that meshes with a sliding toothed bar - converting rotary motion to reciprocating (to- and- fro)






12. Describes the limitations and requirements of the project's solution

24. Provides direction for the work of the designer






25. Ways of overcoming difficulties






26. The generation of ideas for solutions






27. A bar or rod that tilts on a pivot - or fulcrum - used to overcome a resistance or to raise a weight when force is applied is a






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






29. A shaft with a screw thread that meshes with a toothed wheel to alter the direction of motion - and change the speed and force






30. The planned process of change






31. A force that opposes motion






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