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. 550 foot- pounds per second






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






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






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






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






7. The metric unit for measuring work






8. The energy of motion






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






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






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






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






14. The scientific formula for work is






15. The ability to do work






16. The English unit of measuring work






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






18. Provides direction for the work of the designer






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






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






21. Provides a framework for design and problem solving work






22. 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?






23. Energy of position






24. The weight or resistance on a lever






25. The development of something completely new






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






27. Provides problem clarification and specification






28. Force times distance






29. The planned process of change






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






31. When a machine multiplies the effort being used






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






33. Ways of overcoming difficulties






34. The improvement of things already invented






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






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






38. The turning point of a lever






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






40. The weight of the obect being moved






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






42. 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






43. Seeks to explain and describe the physical world






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






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






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






47. The difficulties we must overcome

49. The generation of ideas for solutions






50. Provides a structure for thinking and doing
