Principles Of Engineering

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 connection points of members of a truss






2. The unit of potential difference symbolized as V






3. Ratio of distance traveled by the applied effort and resistance force within a system.






4. Test methods used to examine an object - material - or system without impairing its future usefulness






5. The geometric center of an area.






6. The transfer of energy by electromagnetic waves






7. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






8. The rotating member of an electrical machine






9. A person or group for which product or service design efforts are intended.






10. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

11. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






12. The collection and analysis of numerical data in large quantities






13. The difference between the maximum and minimum dimensions allowed within the design of a product.






14. The result of an experiment






15. A device that holds the compressed air in a pneumatic system.






16. Used to transport fluid in a circuit






17. An energy source that will never run out






18. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






19. The information produced by a computer






20. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






21. The value that occurs most frequently






22. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






23. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






24. The collection - evaluation - and interpretation of data






25. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






26. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






27. Stages a product goes through from concept and use to eventual withdrawal from the market place.






28. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






29. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






30. A toothed wheel whose teeth engage the links of a chain.






31. A support that prevents translation in any direction






32. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






33. Amount of difference between a value and the mean.






34. The condition of unrestrained motion in a gravitational field.






35. Frequency distibution graph






36. Not having fixed limits; unrestricted; broad






37. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






38. A negative temperature coefficient - also known as a thermistor - is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature.






39. Any device that controls - either automatically or manually - the flow of a fluid.






40. Plant materials and animal waste used especially as a source of fuel.






41. Graphical representation of a material's mechanical properties






42. The measure of resistance to heat flow






43. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






44. The ratio of the magnitude of the resistance and effort forces applied a system.






45. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






46. A device that responds to a physical stimulus






47. A system that links electricity produced in power stations to deliver it to where it is needed






48. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






49. A force that produces or tends to produce rotation or torsion.






50. A body subjected to a push.
