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 difficulties we must overcome






2. Shows what a product will look like when it is produced






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






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






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






6. The English unit of measuring work






7. The improvement of things already invented






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






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






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






11. A wheel fixed to a support with a rope that is run over the wheel to change the direction of a force applied to the rope






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






13. 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






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






15. The generation of ideas for solutions






16. The weight of the obect being moved






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






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






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






20. Ways of overcoming difficulties






21. An inclined plane which is wrapped around a cylinder






22. The energy of motion






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






24. Seeks to explain and describe the physical world






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

34. Which is not a true statement about gears?






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






36. The turning point of a lever






37. 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






38. The force applied to a lever






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






40. The scientific formula for work is

43. Force times distance






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






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






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