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






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






3. Categorical data graph






4. Used to transport fluid in a circuit






5. The amount or quantity of something






6. The measure of resistance to heat flow






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






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






9. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

10. A valve that allows flow in one direction but prevents flow in the opposite direction.






11. A solid- state switching device.






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






13. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






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






15. Ratio of distance traveled by the applied effort and resistance force within a system.






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






17. Not having fixed limits; unrestricted; broad






18. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






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






20. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






21. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






22. The distance the fluid travels through a system in a given period of time.






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






24. A statsitical measurement of variability






25. Any alteration of shape or dimensions of a body caused by stresses - thermal expansion or contraction - chemical or metallurgical transformations - or shrinkage and expansions due to moisture change






26. A support that prevents translation in any direction






27. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

28. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






29. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






30. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






31. The value that occurs most frequently






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






33. Numbers or information describing some characteristic.






34. The collection - evaluation - and interpretation of data






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






36. The geometric center of an area.






37. Arithmetic average






38. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

39. Bell- shaped probability distribution






40. The condition or quality of being true - correct - or exact; precision; exactness.






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






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. 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






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






45. Energy caused by the movement of electrons.






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






47. 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.

48. A device used to spray an oil mist into the stream of a pneumatic system.






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






50. Absolute temperature scale
