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 physical quantity that has magnitude only.






2. Conversion of a digital signal to its analog equivalent - such as a voltage.






3. The measure of resistance to heat flow






4. 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






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






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






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






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






9. 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.






10. 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.

11. A device that holds the compressed air in a pneumatic system.






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






13. A force system where all of the forces are applied at a common point on the body or having their lines of action with a common intersection point.






14. Categorical data graph






15. 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






16. Distance between adjacent threads in a screw.






17. 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






18. A general agreement






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






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






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






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






23. The contact of a relay that is closed when the coil is de- energized.






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






25. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






26. A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work






27. Categorical data graph percentage






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






29. A specialized heavy- duty computer system used for process control in factories - chemical plants - and warehouses






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






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






32. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






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






34. The law that if two bodies are in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other






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






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






37. A toothed wheel whose teeth engage the links of a chain.






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






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






40. A control system that considers the output of a system and makes adjustments based on that output.






41. The rate at which work is performed or energy is expended






42. Produced by the combining of parts or elements to form a whole - rather than of natural origin; not real - artificial






43. 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






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






45. A system that links electricity produced in power stations to deliver it to where it is needed






46. Used to transport fluid in a circuit






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






48. The use of heat from within the Earth or from the atmosphere near oceans






49. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






50. A resource that cannot be replaced once used
