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. A force that opposes motion






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






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






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






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






6. Seeks to explain and describe the physical world






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






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






9. Force times distance






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






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






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






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






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






15. The force applied to a lever






16. Which is not a true statement about gears?






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






18. The English unit of measuring work






19. 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






20. Provides a structure for thinking and doing






21. The generation of ideas for solutions






22. The development of something completely new






23. The weight of the obect being moved






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






25. Ways of overcoming difficulties






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






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






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






29. 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






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






31. When a machine multiplies the effort being used






32. 550 foot- pounds per second






33. Provides a framework for design and problem solving work






34. The weight or resistance on a lever






35. The metric unit for measuring work






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






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






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






39. 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






40. The planned process of change






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






42. 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?






43. Energy of position






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






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






46. Provides problem clarification and specification
