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






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






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

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






6. Numbers or information describing some characteristic.






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






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






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






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

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






14. The type of charge an atomic particle has






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






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






17. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

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






22. The geometric center of an area.






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






24. The net transfer of electric charge (electron movement along a path) per unit of time.






25. Energy caused by the movement of electrons.






26. The collection - evaluation - and interpretation of data






27. 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






28. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






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






30. The measure of resistance to heat flow






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






32. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






33. A statsitical measurement of variability






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






35. 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.






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






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






38. A body subjected to a push.






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






40. A device used to remove contamination from a fluid






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






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






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






44. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






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






46. 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






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






48. A device that responds to a physical stimulus
