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 law that states all natural processes proceed in a preferred direction






2. 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






3. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






4. 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.

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






6. 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






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






8. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






9. A systemized body of laws; a set of principles - as of ethics






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






11. 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






12. The rate at which work is performed or energy is expended






13. A form of energy that travels through space as waves.






14. Categorical data graph






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






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






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






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






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






20. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






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






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






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






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






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






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






27. The measure of resistance to heat flow






28. A support that prevents translation in any direction






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






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






31. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






32. Bell- shaped probability distribution






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






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






35. The square root of the variance.






36. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






38. The connection points of members of a truss






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






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






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






42. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






43. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






44. A solid- state switching device.






45. The result of an experiment






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






47. A resource that can be replaced when needed






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






49. The difference between samples






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