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






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






3. A law that states all natural processes proceed in a preferred direction






4. Values that possess names or labels






5. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






6. The total length of path over which the particle travels.






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






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






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






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






11. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






12. A part of the physical world as described by its thermodynamic properties such as temperature - volume - pressure - concentration - surface tension - and viscosity.






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






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






15. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






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






17. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






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






19. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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






21. 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






22. 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.

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






24. A toothed wheel whose teeth engage the links of a chain.






25. Numbers or information describing some characteristic.






26. 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.






27. 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.






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






29. A device that holds the compressed air in a pneumatic system.






30. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






31. Stages a product goes through from concept and use to eventual withdrawal from the market place.






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






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






34. A resource that can be replaced when needed






35. Energy derived from sources that do not use up natural resources or harm the environment






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






37. The information produced by a computer






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






39. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






41. A subordinate routine; specifically - a sequence of computer instructions for performing a specified task that can be used repeatedly.






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






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






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






45. The result of an experiment






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






47. Arithmetic average






48. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






49. Used to transport fluid in a circuit






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