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






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






3. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






4. The calculated likelihood that a given event will occur






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






6. 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.






7. 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






8. A device used to spray an oil mist into the stream of a pneumatic system.






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






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






11. Used to start and stop flow in a circuit






12. A support that prevents translation in any direction






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






14. Frequency distibution graph






15. 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.






16. A written plan that identifies a problem to be solved - its criteria - and its constraints.






17. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






18. A part or element of a larger whole






19. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






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






21. 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.






22. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






23. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

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






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






26. The use of quality control techniques associated with a process.






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






28. Categorical data graph percentage






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 device that responds to a physical stimulus






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






32. The use of a fluid (liquid or gas) to transmit power from one location to another.






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






34. Not having fixed limits; unrestricted; broad






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






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






37. The flow of electrical power or charge.






38. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






39. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






40. Conversion of a digital signal to its analog equivalent - such as a voltage.






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






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






43. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






45. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






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






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






48. The probability of satisfactory operation of the product in a given environment over a specified time interval.






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






50. Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance
