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






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






3. Which is not a true statement about gears?






4. A force that opposes motion






5. An inclined plane which is wrapped around a cylinder






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






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






8. Seeks to explain and describe the physical world






9. 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






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






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






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






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






14. Force times distance






15. 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?






16. The weight or resistance on a lever






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






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






19. Provides direction for the work of the designer






20. 550 foot- pounds per second






21. Energy of position






22. 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






23. The ability to do work






24. The force applied to a lever






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






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






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






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






29. Work divided by time






30. 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






31. The planned process of change






32. The generation of ideas for solutions






33. More than one pulley working together






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






35. The improvement of things already invented






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






37. The difficulties we must overcome






38. Changes and improvements made to products already invented are






39. Provides a framework for design and problem solving work






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






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






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






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






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






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






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






47. Ways of overcoming difficulties






48. The energy of motion






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






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