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. Provides a framework for design and problem solving work






2. The scientific formula for work is






3. Changes and improvements made to products already invented are

5. The weight of the obect being moved






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






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






8. The turning point of a lever






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






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






11. The metric unit for measuring work






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






13. Provides problem clarification and specification






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






15. Consists of an endless chain looped around three pulleys






16. When a machine multiplies the effort being used






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






18. The improvement of things already invented






19. 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?






20. The English unit of measuring work






21. Seeks to explain and describe the physical world






22. The planned process of change






23. Provides a structure for thinking and doing






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






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






26. The generation of ideas for solutions






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






28. The weight or resistance on a lever

30. 550 foot- pounds per second






31. 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






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






33. 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






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






35. Work divided by time






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






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






38. Which is not a true statement about gears?






39. The ability to do work






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






41. Ways of overcoming difficulties






42. 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






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






44. The difficulties we must overcome






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






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






47. Energy of position






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






49. 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






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