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 probability of an event occurring based upon other event probabilities


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






3. The net transfer of electric charge (electron movement along a path) per unit of time.






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






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






6. An energy source that will never run out






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






8. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






9. The contact of a relay that is open when the coil is de- energized






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






11. 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






12. Used to transport fluid in a circuit






13. 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






14. The fixed point around which a lever rotates.






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






16. Categorical data graph






17. The law stating that the stress of a solid is directly proportional to the strain applied to it


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






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






20. A switch that can provide variable motion control






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






22. A physical quantity that has magnitude only.






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






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






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






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






27. A general agreement






28. Pressure exerted by a confined fluid acts undiminished equally in all directions


29. Energy derived from sources that do not use up natural resources or harm the environment






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






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






32. 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.






33. Not having fixed limits; unrestricted; broad






34. A device that holds the compressed air in a pneumatic system.






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






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






37. 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






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






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






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






41. The contact of a relay that is closed when the coil is de- energized.






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






43. A system of discrete states: high or low - on or off - 1 or 0.






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






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






46. Graphical representation of a material's mechanical properties






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






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






49. 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.






50. A resource that can be replaced when needed
