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 gear positioned between the driver and the driven gear used to change rotational direction.






2. Changing one form of energy to another






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






4. 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.






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






6. A written plan that identifies a problem to be solved - its criteria - and its constraints.






7. Energy caused by the movement of electrons.






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






9. The measure of resistance to heat flow






10. The resistance that one surface or object encounters when moving over another.






11. A support that prevents translation in any direction






12. A switch that can provide variable motion control






13. 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.






14. 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.






15. A form of energy that travels through space as waves.






16. The production of electricity in conductors with the use of magnets






17. A statsitical measurement of variability






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






19. A type of system that uses circulating pumps and fans to collect and distribute heat.






20. Values that possess names or labels






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






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






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






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






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






26. Frequency distribution graph






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






28. Used to start and stop flow in a circuit






29. A support that only prevents a beam from translating in one direction.






30. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






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






32. 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






33. 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






34. 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






35. 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.






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






37. A general agreement






38. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






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






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






41. Distance between adjacent threads in a screw.






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






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






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






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






46. 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






47. The use of a fluid (liquid or gas) to transmit power from one location to another.






48. A person or group for which product or service design efforts are intended.






49. The square root of the variance.






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