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






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






3. 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






4. The improvement of things already invented






5. The generation of ideas for solutions






6. When a machine multiplies the effort being used






7. The ability to do work






8. Changes and improvements made to products already invented are






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






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






11. Ways of overcoming difficulties






12. 550 foot- pounds per second






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






14. Work divided by time






15. The force applied to a lever






16. The planned process of change






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






18. Provides problem clarification and specification






19. Provides a structure for thinking and doing






20. The weight or resistance on a lever






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






22. An inclined plane which is wrapped around a cylinder






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






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






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






26. 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






27. Consists of an endless chain looped around three pulleys






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






29. Provides direction for the work of the designer






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






31. The energy of motion






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






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






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






35. The turning point of a lever






36. Force times distance






37. A pulley that makes work easier






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






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






40. The metric unit for measuring work






41. More than one pulley working together






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






43. 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






44. Provides a framework for design and problem solving work






45. The English unit of measuring work






46. The difficulties we must overcome






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






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






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






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