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. Used to start and stop flow in a circuit






2. 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






3. 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






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






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






6. Those properties of a material that reveal the elastic and inelastic reaction when force is applied - or that involve the relationship between stress and strain; for example - the modulus of elasticity - tensile strength - and fatigue limit

11. Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially - a structural material made of pla






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






13. 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






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






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






16. A general agreement






17. Degree of conformity of a measure to a standard value.






18. A plate or bracket for strengthening an angle in framework.






19. The fixed point around which a lever rotates.






20. The connection points of members of a truss






21. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces






22. 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.






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






24. The flow of electrical power or charge.






25. A law that states that the internal energy in a system remains constant and the change in thermal energy of a system is equal to the work done on the system.






26. Values that represent a measurable quantity






27. A systemized body of laws; a set of principles - as of ethics






28. An external force applied to an object.






29. Systems that do not make use of any externally powered - moving parts - such as circulation pumps - to move heated water or air.






30. The unit of potential difference symbolized as V






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






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






33. A switching device that uses the magnetic field generated by an electrical current for actuation.






34. 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






35. A support that only prevents a beam from translating in one direction.






36. 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.






37. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






38. The resultant of a system of force is the vector sum of all forces.






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






40. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






41. A device used to remove contamination from a fluid






42. The law stating that the stress of a solid is directly proportional to the strain applied to it

43. A support that prevents translation in any direction






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






45. A measure of how easily a material can be twisted






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






47. The resistance that one surface or object encounters when moving over another.






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






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






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