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. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






2. Measure of variation equal to the sum of the deviations of each value from the mean.






3. The resultant of a system of force is the vector sum of all forces.






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






5. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






6. 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.






7. A body subjected to pull.






8. Changes one form of power to another






9. A device for making - breaking - or changing the connections in an electrical circuit.






10. A profession for which one trains and which is undertaken as a permanent calling.






11. Impeding effect exerted by one material object on another.






12. The total pressure exerted on a system - including atmospheric pressure.






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






14. Slender straight pieces of a truss connected by joints.






15. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






16. 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.






17. The calculated likelihood that a given event will occur






18. A device used to measure flow rate.






19. Values that represent a measurable quantity






20. A circuit in which all parts are connected end to end to provide a single path of current






21. A process that changes the size and shape of a material by a combination of force and a shaped form






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






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






24. The resistance that one surface or object encounters when moving over another.






25. The absolute value of a number






26. A control circuit in which the system output has no effect on the control






27. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






28. The volume of fluid that moves through a system in a given period of time.






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






30. A general agreement






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






32. An external force applied to an object.






33. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






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






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






36. Distance between adjacent threads in a screw.






37. 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.






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






39. Numbers or information describing some characteristic.






40. Two different sized circular objects that are attached together and turn as one.






41. Frequency distibution graph






42. The measurement of how difficult it is for charges to flow through a material






43. The information produced by a computer






44. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






45. The opposition that a device or material offers to the flow of direct current






46. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






47. Change in length of an object in some direction per unit






48. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






49. 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






50. The unit of potential difference symbolized as V
