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






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






3. The force applied to a lever






4. 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






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






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






7. Provides a framework for design and problem solving work






8. Provides direction for the work of the designer






9. The metric unit for measuring work






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






11. Which is not a true statement about gears?






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






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






14. 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






15. Force times distance






16. The scientific formula for work is






17. Provides problem clarification and specification






18. Energy of position






19. A pulley that makes work easier






20. An inclined plane which is wrapped around a cylinder






21. Consists of an endless chain looped around three pulleys






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






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






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






25. 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






26. 550 foot- pounds per second






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






28. A force that opposes motion

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






31. When a machine multiplies the effort being used






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






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






34. Provides a structure for thinking and doing






35. The planned process of change






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






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






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