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 study of how human beings best interact with technology






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






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






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






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






6. The weight of the obect being moved






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






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






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






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






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

13. 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?






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






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






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






17. Provides problem clarification and specification






18. Energy of position






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






20. Force times distance






21. Work divided by time






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






23. An inclined plane which is wrapped around a cylinder






24. Ways of overcoming difficulties






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






26. The force applied to a lever






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






28. The metric unit for measuring work






29. Which is not a true statement about gears?






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






31. 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






32. The ability to do work






33. The planned process of change






34. The weight or resistance on a lever






35. The energy of motion






36. A force that opposes motion
