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 value that occurs most frequently






2. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






3. The amount or quantity of something






4. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






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






6. The unit of potential difference symbolized as V






7. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






8. 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






9. A tool for systematically ranking alternatives according to a set of criteria.






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






11. A control system that considers the output of a system and makes adjustments based on that output.






12. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






13. Two different sized circular objects that are attached together and turn as one.






14. 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






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






16. 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






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






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






19. Changing one form of energy to another






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






21. Categorical data graph






22. Maximum stress that a material will withstand without permanent deformation






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






24. Categorical data graph percentage






25. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






26. Information fed into a data processing system or computer.






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






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






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






30. The difference between samples






31. A switching device that uses the magnetic field generated by an electrical current for actuation.






32. The flow of electrical power or charge.






33. 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.






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






35. A statsitical measurement of variability






36. The collection - evaluation - and interpretation of data






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






38. 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.






39. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






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






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






42. 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






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






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






45. Any device that controls - either automatically or manually - the flow of a fluid.






46. The fixed point around which a lever rotates.






47. A gear positioned between the driver and the driven gear used to change rotational direction.






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






49. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






50. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.
