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. Operational models used to test the mechanical or electrical systems






2. More than one pulley working together






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






4. The force applied to a lever






5. Provides a framework for design and problem solving work






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






7. Provides problem clarification and specification






8. Provides a structure for thinking and doing






9. A force that opposes motion






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






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






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






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






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






15. Ways of overcoming difficulties






16. The scientific formula for work is






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






18. Provides direction for the work of the designer






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






20. 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?






21. Changes and improvements made to products already invented are






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






24. Consists of an endless chain looped around three pulleys






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






26. Work divided by time






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






28. The English unit of measuring work






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






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






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






32. The weight or resistance on a lever






33. An inclined plane which is wrapped around a cylinder






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






35. The weight of the obect being moved






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






37. When a machine multiplies the effort being used






38. The energy of motion






39. Energy of position






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






41. The improvement of things already invented






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






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

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






46. The development of something completely new






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






48. The planned process of change






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






50. Seeks to explain and describe the physical world
