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






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






3. A solid- state switching device.






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






5. The force per unit area exerted by a fluid against a surface






6. A general agreement






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






8. Distance between adjacent threads in a screw.






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

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






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






12. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






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

14. The unit of potential difference symbolized as V






15. Values that represent a measurable quantity






16. 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






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






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






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






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






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






22. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






23. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






24. A statsitical measurement of variability






25. Categorical data graph percentage






26. 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.






27. An air pump that compresses air into a receiver tank.






28. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






29. 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.






30. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






31. A device used to convert fluid power into mechanical power in the form of linear motion.






32. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






33. Not having fixed limits; unrestricted; broad






34. The measure of resistance to heat flow






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






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






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






38. Middle value of a set of values arranged in order of magnitude.






39. 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






40. Values that possess names or labels






41. The process of creating an object by adding small pieces or layers together to make a final product






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






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






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






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






46. 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.






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






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






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






50. A straight line that comes closest to the points on a scatter plot
