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. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






2. Anything for which a person is legally bound or responsible






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






4. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






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






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






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






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






9. Values that possess names or labels






10. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






11. A truss that lies in a single plane often used to support roofs and bridges






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






13. The condition of a string - wire - or rod that is stretched between two points






14. The fractional increase in a material's length due to stress in tension or thermal expansion






15. A support that only prevents a beam from translating in one direction.






16. The transfer of energy by electromagnetic waves






17. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






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






19. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






20. The basic unit of electric current adopted under the Systeme International d'Unites






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






22. The distance the fluid travels through a system in a given period of time.






23. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






24. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

25. 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






26. Changes one form of power to another






27. The fixed point around which a lever rotates.






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






29. 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






30. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






31. Absolute temperature scale






32. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






33. Used to start and stop flow in a circuit






34. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






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






36. A device that responds to a physical stimulus






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






38. A group of machined or handmade parts that fit together to form a self- contained unit.






39. A control system that considers the output of a system and makes adjustments based on that output.






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






41. The ratio of actual strength to required strength






42. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






43. Individual fuel cells that are combined in series.






44. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






45. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






46. The value that occurs most frequently






47. The collection - evaluation - and interpretation of data






48. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






49. 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.






50. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work
