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. Changes one form of power to another






2. A device used to remove contamination from a fluid






3. The difference between samples






4. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






5. A resource that cannot be replaced once used






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






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






8. 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






9. The transfer of heat through matter by molecular activity; Energy is transferred through collisions from one molecule to another






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






11. 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






12. 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.






13. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






14. Energy caused by the movement of electrons.






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






16. The magnitude of the total distance traveled divided by the time elapsed.






17. The unit of potential difference symbolized as V






18. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






19. 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






20. A set of all possible outcomes or events in an experiment that cannot be further broken down.






21. Distance between adjacent threads in a screw.






22. A support that prevents translation in any direction






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






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






25. Not having fixed limits; unrestricted; broad






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






27. 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






28. 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.






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






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






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






32. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






33. A measure of how easily a material can be twisted






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






35. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






36. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






37. The ratio of actual strength to required strength






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






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






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






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






42. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






43. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.

44. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






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






46. A device used to measure flow rate.






47. 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.






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






49. The result of an experiment






50. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla
