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. Any alteration of shape or dimensions of a body caused by stresses - thermal expansion or contraction - chemical or metallurgical transformations - or shrinkage and expansions due to moisture change






2. Information fed into a data processing system or computer.






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






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






5. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






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






7. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






8. The information produced by a computer






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






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






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

12. 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






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






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






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






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






17. Not having fixed limits; unrestricted; broad






18. Categorical data graph percentage






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






20. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit






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






22. A signal having the characteristic of being continuous and changing smoothly over a given range - rather than switching suddenly between certain levels






23. A body subjected to pull.






24. A device used to remove contamination from a fluid






25. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

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






27. Change in length of an object in some direction per unit






28. A part of a design brief that challenges the designer - describes what a design solution should do without describing how to solve the problem -






29. A mechanical property of a material that shows how effective the material is absorbing mechanical energy without sustaining any permanent damage






30. A general agreement






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






32. Amount of difference between a value and the mean.






33. 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.






34. Individual fuel cells that are combined in series.






35. 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.






36. The measure of resistance to heat flow






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






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






39. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

40. A support that prevents translation in any direction






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






42. A switch that can provide variable motion control






43. A device used to create flow in a hydraulic system.






44. Graphical representation of a material's mechanical properties






45. A force that produces or tends to produce rotation or torsion.






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






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






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






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






50. An energy source that will never run out
