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 improvement of things already invented






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






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






4. Provides problem clarification and specification






5. The development of something completely new






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






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






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






9. Ways of overcoming difficulties






10. The planned process of change






11. The difficulties we must overcome






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






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






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






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






16. Changes and improvements made to products already invented are






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






18. Consists of an endless chain looped around three pulleys






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






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






21. 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






22. 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






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






24. The English unit of measuring work






25. The weight of the obect being moved






26. Provides direction for the work of the designer






27. The metric unit for measuring work






28. A pulley that makes work easier






29. The energy of motion






30. More than one pulley working together






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






32. Which is not a true statement about gears?






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






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






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






36. Energy of position






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






38. An inclined plane which is wrapped around a cylinder






39. The ability to do work






40. The weight or resistance on a lever






41. A wheel that meshes with a sliding toothed bar - converting rotary motion to reciprocating (to- and- fro)






42. A force that opposes motion






43. Work divided by time






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






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






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






47. The turning point of a lever






48. When a machine multiplies the effort being used






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






50. When generating ideas for a solution to a problem - it is important to do which of the following in order to effectively and visually communicate these ideas for use in construction drawings?
