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






2. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






3. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






4. The rate of change of velocity with respect to time.






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






6. A form of energy that travels through space as waves.






7. The ratio of actual strength to required strength






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






9. A dynamo or similar machine for converting mechanical energy into electricity






10. A vector quantity that includes the speed and direction of an object.






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






12. A general agreement






13. The use of heat from within the Earth or from the atmosphere near oceans






14. A resource that can be replaced when needed






15. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






16. The tank that holds the fluid in a hydraulic system.






17. The total length of path over which the particle travels.






18. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






19. A part of the physical world as described by its thermodynamic properties such as temperature - volume - pressure - concentration - surface tension - and viscosity.






20. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






21. The process of creating an object by adding small pieces or layers together to make a final product






22. The calculated likelihood that a given event will occur






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






24. A measure of a fluid's thickness or resistance to flow.






25. The return to the input of a part of the output of a machine - system - or process






26. Energy derived from sources that do not use up natural resources or harm the environment






27. Energy caused by the movement of electrons.






28. The state when objects are not yet in motion






29. Pressure exerted by a confined fluid acts undiminished equally in all directions


30. A tool for systematically ranking alternatives according to a set of criteria.






31. The measure of resistance to heat flow






32. Numbers or information describing some characteristic.






33. The contact of a relay that is open when the coil is de- energized






34. The contact of a relay that is closed when the coil is de- energized.






35. The reason for which something is done or for which something exists.






36. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






37. Energy which a body possesses by virtue of being in motion






38. A truss composed of triangles - which will retain its shape even when removed from supports.






39. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






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






41. A set of all possible outcomes or events in an experiment that cannot be further broken down.






42. Not having fixed limits; unrestricted; broad






43. The amount or quantity of something






44. 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.






45. The information produced by a computer






46. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






47. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






48. A quantity that has both a magnitude and direction.






49. An inclined plane wrapped around a cylinder - forming the path and pitch.






50. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.
