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.

2. The weight of the obect being moved






3. The English unit of measuring work






4. Which is not a true statement about gears?






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

9. Consists of an endless chain looped around three pulleys






10. More than one pulley working together






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






12. Energy of position






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






14. Energy may change form but the amount of energy remains the same






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






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






17. A guide to help make problem solving in technology more effective






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






19. Levers in which the fulcrum is always placed between the effort and the load are called






20. 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






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






22. A force that opposes motion






23. The improvement of things already invented






24. A fixed wheel with a rope or chain that is attached to a load - used to change the direction of a force or to lift heavy objects - is a






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






26. A pulley that changes direction of effort but provides no mechanical advantage






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

35. Force times distance






36. Two gear wheels that intermesh in the same plane - regulating the speed or force of motion and reversing its direction






37. The generation of ideas for solutions






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