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 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






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






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






4. Which is not a true statement about gears?






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






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

17. Seeks to meer our needs and wants and to extend our capabilities






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






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






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






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

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






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






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






33. The ability to do work






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






35. An inclined plane which is wrapped around a cylinder






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