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 weight or resistance on a lever






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






3. 550 foot- pounds per second






4. The difficulties we must overcome






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






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






7. Seeks to explain and describe the physical world






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






9. The generation of ideas for solutions






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






11. Work divided by time






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






13. The English unit of measuring work






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






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






16. Which is not a true statement about gears?






17. 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






18. More than one pulley working together






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






20. An inclined plane which is wrapped around a cylinder






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






22. The scientific formula for work is






23. Provides direction for the work of the designer






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






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






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






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






28. Energy of position

30. Provides a framework for design and problem solving work






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






32. The planned process of change






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






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






35. A force that opposes motion






36. 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






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






38. The ability to do work






39. The turning point of a lever






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






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






42. When a machine multiplies the effort being used






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

45. Ways of overcoming difficulties






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






47. 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






48. 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
