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 general agreement






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






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






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






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






6. A photo- sensitive resistor whose resistance decreases as the light striking the unit increases.






7. The transfer of energy by electromagnetic waves






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






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






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






11. A body subjected to a push.






12. 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.






13. A part of an axle or shaft bent out at right angles - for converting reciprocal to circular motion and vice versa.






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






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






16. 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.






17. 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






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






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






20. The collection - evaluation - and interpretation of data






21. A device used to measure flow rate.






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






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






24. A vector quantity that includes the speed and direction of an object.






25. The information produced by a computer






26. Point at which the deformation is no longer directly proportional to the applied force. Hooke's Law no longer applies






27. The state when objects are not yet in motion






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






29. A cylinder that acts under pressure in one direction only and returns automatically when the pressure is released.






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






31. An energy source that will never run out






32. 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.






33. A quantity that has both a magnitude and direction.






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






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






36. 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.






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. Measure of data scatter






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






40. The measurement of how difficult it is for charges to flow through a material






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






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






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






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






45. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






46. A form of energy that travels through space as waves.






47. Measure of variation equal to the sum of the deviations of each value from the mean.






48. Bell- shaped probability distribution






49. A group of machined or handmade parts that fit together to form a self- contained unit.






50. The ratio of actual strength to required strength
