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






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






3. Provides a structure for thinking and doing






4. The development of something completely new






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






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






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






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






9. 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






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






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

13. 550 foot- pounds per second






14. A machine in which a lever rotates around a fixed point






15. Which is not a true statement about gears?






16. 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

22. Machines are used to make work easier. How does a machine accomplish this?






23. Consists of an endless chain looped around three pulleys






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






25. The weight or resistance on a lever






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






27. The energy of motion

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






31. A force that opposes motion






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