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






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






3. The type of charge an atomic particle has






4. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






5. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus






6. The result of an experiment






7. A machine for producing power in which a wheel or rotor is made to revolve by a fast- moving flow of water - steam - gas - or air






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






9. The sense of a vector is the direction of the vector relative to its path and indicated by the location of the arrow.






10. The difference between the maximum and minimum dimensions allowed within the design of a product.






11. Energy caused by the movement of electrons.






12. Categorical data graph






13. The fractional increase in a material's length due to stress in tension or thermal expansion






14. A written plan that identifies a problem to be solved - its criteria - and its constraints.






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






16. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






17. The state when objects are not yet in motion






18. 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






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






20. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






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






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






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






24. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






25. 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.






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






27. Absolute temperature scale






28. Not having fixed limits; unrestricted; broad






29. Measure of data scatter






30. Distance between adjacent threads in a screw.






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






32. Values that represent a measurable quantity






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






34. A systemized body of laws; a set of principles - as of ethics






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






36. Slender straight pieces of a truss connected by joints.






37. A continuous band of tough flexible material used to transmit motion and power within a pulley system.






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






39. The total pressure exerted on a system - including atmospheric pressure.






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






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






42. A subset of a sample space






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






44. 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






45. The stress required to fracture a material whether by compression - tension - or shear






46. Graphical representation of a material's mechanical properties






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






48. 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.






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






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