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. Frequency distribution graph






2. The condition of unrestrained motion in a gravitational field.






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






4. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






5. The flow of electrical power or charge.






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






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






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






9. The type of charge an atomic particle has






10. The calculated likelihood that a given event will occur






11. The fixed point around which a lever rotates.






12. 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.

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






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






15. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going






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






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






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






19. States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit

20. Slender straight pieces of a truss connected by joints.






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






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






23. 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.






24. The place at which independent and often unrelated systems meet and act on or communicate with each other.






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






26. Frequency distibution graph






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






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






29. SPC is a method of monitoring - controlling - and ideally improving a process through statistical analysis. Its four basic steps include measuring the process - eliminating variances in the process to make it consistent - monitoring the process - and






30. The transfer of heat by the movement of a mass or substance; it can take place only in fluids






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






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

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






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






35. A part of a design brief that clearly and concisely identifies a client's or target consumer's problem - need - or want.






36. A surface or shape exposed by making a straight cut through something at right angles to the axis.






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






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






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






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






41. 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.






42. The result of an experiment






43. 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






44. Values that represent a measurable quantity






45. A part or element of a larger whole






46. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






47. 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






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






49. The volume of a gas at constant temperature varies inversely with the pressure exerted on it.
