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 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.






2. 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.






3. A result of a force moving an object a certain distance






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






5. A small circuit board that controls all the processing within a computer.






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






7. A switch that can provide variable motion control






8. 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.






9. Categorical data graph percentage






10. The state when objects are not yet in motion






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






12. A solid- state switching device.






13. 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.






14. A support that prevents translation in any direction






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






16. The production of electricity in conductors with the use of magnets






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






18. Not having fixed limits; unrestricted; broad






19. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






20. 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.






21. 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






22. Frequency distribution graph






23. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






24. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






25. The fixed point around which a lever rotates.






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






27. The calculated likelihood that a given event will occur






28. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






29. Graphical representation of a material's mechanical properties






30. Energy derived from sources that do not use up natural resources or harm the environment






31. Used to control which path fluid takes in a circuit.






32. Used to start and stop flow in a circuit






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






34. A control circuit in which the system output has no effect on the control






35. An electromagnetically operated switching device.






36. Arithmetic average






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






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






39. The reason for which something is done or for which something exists.






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






41. The place at which independent and often unrelated systems meet and act on or communicate with each other.






42. Values that represent a measurable quantity






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






44. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






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






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






47. The difference between samples






48. The amount or quantity of something






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






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