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






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






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






4. Individual fuel cells that are combined in series.






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






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






7. 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.


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






9. A plate or bracket for strengthening an angle in framework.






10. A part or element of a larger whole






11. An inclined plane wrapped around a cylinder - forming the path and pitch.






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






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






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






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






16. A device used to remove contamination from a fluid






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






18. The square root of the variance.






19. The law stating that the stress of a solid is directly proportional to the strain applied to it


20. 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






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






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






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






24. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






25. The tank that holds the fluid in a hydraulic system.






26. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






27. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






28. 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






29. A device that responds to a physical stimulus






30. The rotating member of an electrical machine






31. 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






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






33. The pressure exerted by the weight of the atmosphere above the point of measurement.






34. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






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






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


38. A device used to create flow in a hydraulic system.






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






40. The result of an experiment






41. 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






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






43. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






44. Slender straight pieces of a truss connected by joints.






45. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






46. Values that represent a measurable quantity






47. Plant materials and animal waste used especially as a source of fuel.






48. 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.






49. Middle value of a set of values arranged in order of magnitude.






50. The calculated likelihood that a given event will occur
