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






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






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






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






5. The ratio of the useful energy delivered by a dynamic system to the energy supplied to it






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






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






8. A switch that can provide variable motion control






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






10. Used to transport fluid in a circuit






11. 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






12. A support that prevents translation in any direction






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






14. 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






15. 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.






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






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






18. Operational techniques necessary to satisfy all quality requirements; includes process monitoring and the elimination of root causes of unsatisfactory product or service quality performance






19. Energy caused by the movement of electrons.






20. To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor






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






22. 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.






23. Categorical data graph percentage






24. Absolute temperature scale






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






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






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






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






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






30. Arithmetic average






31. A closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit






32. A device that holds the compressed air in a pneumatic system.






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






34. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






35. The collection and analysis of numerical data in large quantities






36. 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.






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






38. Not having fixed limits; unrestricted; broad






39. 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






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






41. The direction of a vector is defined by the angle between a reference axis and the arrow's line of direction.






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






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






44. A resource that cannot be replaced once used

46. The ratio of actual strength to required strength






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






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






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






50. The result of an experiment
