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






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






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






4. A person or group for which product or service design efforts are intended.






5. Changing one form of energy to another






6. The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body






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






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






9. Changes one form of power to another






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






11. Creating - designing - and transmitting technical information so that people can understand it easily and use it safely - effectively - and efficiently.






12. 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.






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

18. An external force applied to an object.






19. A statsitical measurement of variability






20. 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






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






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






23. 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






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






25. Categorical data graph






26. Used to start and stop flow in a circuit






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






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






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






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






31. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






33. A resource that can be replaced when needed






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






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






36. A device used to convert fluid power into mechanical power in the form of linear motion.






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






38. 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.

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






40. A collection of individuals - each with his or her own expertise - brought together to benefit a common goal.






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






42. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






43. A method of analysis of trusses which constructs free body diagrams of each joint and determines the forces acting in that joint by considering equilibrium of the joint pin.






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






45. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






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






47. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






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






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






50. An activity with observable results
