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.

2. Values that possess names or labels






3. Stages a product goes through from concept and use to eventual withdrawal from the marketplace






4. The state when objects are not yet in motion






5. Categorical data graph






6. The magnitude of the total distance traveled divided by the time elapsed.






7. Not having fixed limits; unrestricted; broad






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






9. 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.






10. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






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






12. 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.






13. A control circuit in which the system output has no effect on the control






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






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






16. A part or element of a larger whole






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






18. A strong rope - usually made of metal - designed to have great tensile strength and to be used in structures.






19. The use of heat from within the Earth or from the atmosphere near oceans






20. 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






21. The use of quality control techniques associated with a process.






22. Impeding effect exerted by one material object on another.






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






24. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

25. Categorical data graph percentage






26. A measure of a fluid's thickness or resistance to flow.






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






28. A subset of a sample space






29. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






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






31. The calculated likelihood that a given event will occur






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






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






34. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






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






36. An inclined plane wrapped around a cylinder - forming the path and pitch.






37. 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






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






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






40. The use of a liquid flowing under pressure to transmit power from one location to another






41. A flat surface set at an angle or an incline with no moving parts that is able to lift objects by pushing or pulling the load.






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






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






44. The value that occurs most frequently






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






46. A negative temperature coefficient - also known as a thermistor - is a sensitive resistor whose primary function is to exhibit a change in electric resistance with a change in temperature.






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






48. Absolute temperature scale






49. A support that prevents translation in any direction






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