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. The rotating member of an electrical machine






2. Used to transport fluid in a circuit






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






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






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






6. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






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






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






9. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






10. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






11. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






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






13. 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






14. The condition of unrestrained motion in a gravitational field.






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






16. Individual fuel cells that are combined in series.






17. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






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






19. An energy source that will never run out






20. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






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






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






23. The difference between samples






24. 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.






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






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






27. 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






28. 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






29. 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.

30. 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.






31. A general agreement






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

33. Measure of data scatter






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






35. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






36. The law stating that the stress of a solid is directly proportional to the strain applied to it

37. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






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






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






40. The collection - evaluation - and interpretation of data






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






42. A system of discrete states: high or low - on or off - 1 or 0.






43. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.
