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. An inclined plane which is wrapped around a cylinder






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

22. The turning point of a lever






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






24. A pulley that makes work easier






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






26. Provides a framework for design and problem solving work






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






28. The metric unit for measuring work






29. Work divided by time






30. The process of how solutions to problems are developed is






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






32. The force applied to a lever






33. When a machine multiplies the effort being used






34. The planned process of change






35. Consists of an endless chain looped around three pulleys






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






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






38. Provides a structure for thinking and doing






39. The English unit of measuring work






40. The weight or resistance on a lever






41. A force that opposes motion






42. The development of something completely new






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






44. The difficulties we must overcome






45. 550 foot- pounds per second






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






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






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






49. Toothed wheels that intermesh with other toothed wheels to transmit motion and force are






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