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 toothed wheel whose teeth engage the links of a chain.






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






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






4. A device used to measure flow rate.






5. Used to start and stop flow in a circuit






6. Not having fixed limits; unrestricted; broad






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






8. 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.






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






10. The opposition that a device or material offers to the flow of direct current






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






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






13. A device that responds to a physical stimulus






14. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






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






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






17. Energy caused by the movement of electrons.






18. A device used to remove contamination from a fluid






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






20. The collection - evaluation - and interpretation of data






21. To monitor and control a process so that the quality of the output/product improves.






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






23. The measure of resistance to heat flow






24. 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






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






26. A person or group for which product or service design efforts are intended.






27. A sliding piece moved by or moving against fluid pressure which usually consists of a short cylindrical body fitting within a cylindrical chamber or vessel along which it moves back and forth.






28. A type of lever that is a wheel with a groove in its rim - which is used to change the direction or multiply a force exerted by a rope or cable.






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






30. A surface or shape exposed by making a straight cut through something at right angles to the axis.






31. The fixed point around which a lever rotates.






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






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






34. The collection and analysis of numerical data in large quantities






35. A physical quantity that has magnitude only.






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






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






38. The geometric center of an area.






39. 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






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






41. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






42. 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.


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






44. A measure of a fluid's thickness or resistance to flow.






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






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






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






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






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






50. The measurement of how difficult it is for charges to flow through a material
