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. Impeding effect exerted by one material object on another.






2. Measure of data scatter






3. Degree of conformity of a measure to a standard value.






4. The elements - constituents - or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized






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






6. 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.






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






8. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






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

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






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






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






13. Test methods used to examine an object - material - or system without impairing its future usefulness






14. Distance between adjacent threads in a screw.






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






16. The total length of path over which the particle travels.






17. The connection points of members of a truss






18. A surface or shape exposed by making a straight cut through something at right angles to the axis.






19. Maximum stress that a material will withstand without permanent deformation






20. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






21. A tool for systematically ranking alternatives according to a set of criteria






22. 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.






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






24. 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






25. The value that occurs most frequently






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






27. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






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






29. 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.






30. An energy source that will never run out






31. A device for making - breaking - or changing the connections in an electrical circuit.






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






33. The flow of electrical power or charge.






34. The structure of or the relationship of the parts in a machine - or in a construction or process comparable to a machine.






35. Not having fixed limits; unrestricted; broad






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






37. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






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






39. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






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






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

43. Listing of a data values along with their corresoponding frequencies.






44. A solid- state switching device.






45. The square root of the variance.






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






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






48. Values that possess names or labels






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






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