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






2. 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.






3. A device used to measure flow rate.






4. The use of quality control techniques associated with a process.






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






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






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






8. Bell- shaped probability distribution






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






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






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






12. Anything for which a person is legally bound or responsible






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






14. Absolute temperature scale






15. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

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






19. The fixed point around which a lever rotates.






20. The volume of fluid that moves through a system in a given period of time.






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






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






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






24. 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.






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






26. The use of a liquid flowing under pressure to transmit power from one location to another






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






28. Values that represent a measurable quantity






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






30. A switch that can provide variable motion control






31. A process that changes the size and shape of a material by a combination of force and a shaped form






32. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






33. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






34. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






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






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






37. A resource that cannot be replaced once used






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






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






40. The collection - evaluation - and interpretation of data






41. Any of various opaque - fusible - ductile - and typically lustrous substances that are good conductors of electricity and heat






42. Distance between adjacent threads in a screw.






43. A quantity that has both a magnitude and direction.






44. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.
