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. The ratio of the magnitude of the resistance and effort forces applied a system.






2. Changes one form of power to another






3. 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






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






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






6. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






7. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






8. The amount or quantity of something






9. A device used to convert fluid power into mechanical power in the form of linear motion.






10. Energy caused by the movement of electrons.






11. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






12. Categorical data graph percentage






13. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






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






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






16. 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






17. Conversion of an analog signal to a digital quantity such as binary.






18. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






19. A truss that lies in a single plane often used to support roofs and bridges






20. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






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






23. The condition of a string - wire - or rod that is stretched between two points






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






25. 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.






26. Energy which a body possesses by virtue of being in motion






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






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






29. An electromagnetically operated switching device.






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






31. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






32. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






33. Machining a surface to size with a fine feed produced in a lathe - milling machine - or grinder






34. Used to control which path fluid takes in a circuit.






35. 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






36. 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.






37. 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.






38. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






39. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






40. A body subjected to a push.






41. The process of creating an object by adding small pieces or layers together to make a final product






42. A control system that considers the output of a system and makes adjustments based on that output.






43. Measure of data scatter






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






45. Categorical data graph






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






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






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






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






50. The geometric center of an area.
