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 machine in which a lever rotates around a fixed point






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






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






4. A force that opposes motion






5. Seeks to explain and describe the physical world






6. The weight of the obect being moved






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






8. When a machine multiplies the effort being used

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






21. The generation of ideas for solutions

29. 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






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






31. 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






32. 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






33. The planned process of change






34. The force applied to a lever






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