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. The development of something completely new






2. 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






3. 550 foot- pounds per second






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






5. The metric unit for measuring work






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






7. Provides a framework for design and problem solving work






8. Force times distance






9. Seeks to explain and describe the physical world






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






11. The scientific formula for work is






12. Ways of overcoming difficulties






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






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






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






16. An inclined plane which is wrapped around a cylinder






17. A pulley that makes work easier






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






19. The force applied to a lever






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






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






22. Provides a structure for thinking and doing






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






24. Provides problem clarification and specification






25. When a machine multiplies the effort being used






26. The English unit of measuring work






27. The planned process of change






28. 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






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






31. Which is not a true statement about gears?






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






33. A guide to help make problem solving in technology more effective






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






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






36. Consists of an endless chain looped around three pulleys






37. Provides direction for the work of the designer






38. A force that opposes motion






39. The improvement of things already invented






40. 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






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






42. The turning point of a lever






43. Come in a variety of sizes with their teeth straight or curved and inclined at a variety of angles






44. Work divided by time






45. Energy of position

47. Describes the limitations and requirements of the project's solution






48. The generation of ideas for solutions






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






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