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.

22. More than one pulley working together






23. Consists of an endless chain looped around three pulleys






24. Work divided by time






25. 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






26. The difficulties we must overcome






27. Seeks to explain and describe the physical world






28. 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






29. 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






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






31. Ways of overcoming difficulties

37. A force that opposes motion






38. The turning point of a lever






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






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






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