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 force (push or pull) used to do work






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






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






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






5. The scientific formula for work is






6. A force that opposes motion






7. The turning point of a lever






8. A pulley that makes work easier






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






10. 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






11. Changes and improvements made to products already invented are






12. Toothed wheels that intermesh with other toothed wheels to transmit motion and force are






13. The amount of effort needed to raise a load by using a pulley system is determined by






14. The metric unit for measuring work






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






16. A bar or rod that tilts on a pivot - or fulcrum






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






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






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






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






21. 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






22. The weight of the obect being moved






23. The difficulties we must overcome






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






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






26. 550 foot- pounds per second






27. The ability to do work






28. Operational models used to test the mechanical or electrical systems






29. Which is not a true statement about gears?






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






31. When generating ideas for a solution to a problem - it is important to do which of the following in order to effectively and visually communicate these ideas for use in construction drawings?






32. Involves the effort you put in and the distance over which you maintain the effort
