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 condition or quality of being true - correct - or exact; precision; exactness.






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






3. A general agreement






4. A truss composed of triangles - which will retain its shape even when removed from supports.






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






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






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






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






9. The probability of satisfactory operation of the product in a given environment over a specified time interval.






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






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






12. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

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






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






15. 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






16. 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






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






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






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






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






21. Information encoded in a digital form - which is usually stored in an assigned address of a data memory for later use by the processor.






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






23. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






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

25. A natural fuel such as coal or gas - formed in the geological past from the remains of living organisms






26. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






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






28. 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.






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






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






31. A result of a force moving an object a certain distance






32. The measure of resistance to heat flow






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






34. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






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






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






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






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






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






40. The force per unit area exerted by a fluid against a surface






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






42. To monitor and control a process so that the quality of the output/product improves.






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






44. 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






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






46. The distance the fluid travels through a system in a given period of time.






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






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






49. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






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