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 device used to spray an oil mist into the stream of a pneumatic system.






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






3. The geometric center of an area.






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






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






6. 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.






7. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

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






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






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






11. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






12. A statsitical measurement of variability






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






14. Maximum stress that a material will withstand without permanent deformation






15. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






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






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






18. 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






19. 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






20. If one object exerts a force on another object - then the second object exerts a force of equal streangth in the opposite direction on the first object.

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






22. The production of electricity in conductors with the use of magnets






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






25. Any of various elementary mechanisms including the lever - the wheel and axle - the pulley - the inclined plane - the wedge - and the screw.






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






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






28. The process in which an electric current is used to produce a chemical reaction - such as the decomposition of water






29. 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






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






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






32. A sketch that shows an object's height - width - and depth in a single view.






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






34. A device used to measure flow rate.






35. An electromagnetically operated switching device.






36. A dynamo or similar machine for converting mechanical energy into electricity






37. 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.






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






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






40. The distance the fluid travels through a system in a given period of time.






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






42. The measure of resistance to heat flow






43. 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.






44. The flow of electrical power or charge.






45. Of or relating to the manufacture of any product (as earthenware - porcelain - or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature






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






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






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






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






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