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






2. The energy that a piece of matter has because of its position or nature or because of the arrangement of parts






3. The connection points of members of a truss






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






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






6. States that the volume of a confined gas is proportional to its temperature - provided its pressure remains constant

7. 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.






8. The volume of fluid that moves through a system in a given period of time.






9. Plant materials and animal waste used especially as a source of fuel.






10. Anything for which a person is legally bound or responsible






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






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






13. Changing one form of energy to another






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






15. The state when objects are not yet in motion






16. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






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






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






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






20. A system of discrete states: high or low - on or off - 1 or 0.






21. The unit of potential difference symbolized as V






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






23. An external force applied to an object.






24. A small circuit board that controls all the processing within a computer.






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






26. 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.






27. 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.






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

31. An energy source that will never run out






32. Categorical data graph percentage






33. A subset of a sample space






34. A truss composed of triangles - which will retain its shape even when removed from supports.






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






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. A device used to create flow in a hydraulic system.






38. A process that changes the size and shape of a material by a combination of force and a shaped form






39. A gear positioned between the driver and the driven gear used to change rotational direction.






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






41. 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






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






43. Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force

47. The square root of the variance.






48. A device for making - breaking - or changing the connections in an electrical circuit.






49. 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.






50. Bell- shaped probability distribution
