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






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






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






4. An inclined plane which is wrapped around a cylinder

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






7. Consists of an endless chain looped around three pulleys






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






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






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






11. Provides direction for the work of the designer






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






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






14. The weight of the obect being moved






15. 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






16. 550 foot- pounds per second






17. Force times distance






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

24. Provides problem clarification and specification






25. The planned process of change






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






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






28. Provides a structure for thinking and doing






29. A pulley that makes work easier






30. 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






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






32. The metric unit for measuring work






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






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






35. The improvement of things already invented






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






37. Energy of position






38. Provides a framework for design and problem solving work






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






40. The scientific formula for work is






41. 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






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






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






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






46. The force applied to a lever






47. The generation of ideas for solutions






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






49. 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?
