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. Frequency distibution graph






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






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






4. A device that responds to a physical stimulus






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






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






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






8. The reason for which something is done or for which something exists.






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


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






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






12. The connection points of members of a truss






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






14. The absolute value of a number






15. The state when objects are not yet in motion






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






17. 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






18. A part or element of a larger whole






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






20. Energy caused by the movement of electrons.






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






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






23. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






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






25. A profession for which one trains and which is undertaken as a permanent calling.






26. A sketch that shows an object's height - width - and depth in a single view.






27. Graphical representation of a material's mechanical properties






28. A dynamo or similar machine for converting mechanical energy into electricity






29. The value that occurs most frequently






30. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






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






32. A straight line that comes closest to the points on a scatter plot






33. A resource that can be replaced when needed






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






35. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force






36. 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






37. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






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






39. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






40. 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






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






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






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






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






45. 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






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






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






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






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






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