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. Provides direction for the work of the designer






2. The weight of the obect being moved






3. The weight or resistance on a lever






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






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






6. The planned process of change






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






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






9. 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

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






30. Seeks to explain and describe the physical world






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






32. When a machine multiplies the effort being used
