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 result of a force moving an object a certain distance






2. The state when objects are not yet in motion






3. Listing of a data values along with their corresoponding frequencies.






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






5. The unit of potential difference symbolized as V






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






7. The rotating member of an electrical machine






8. The ratio of useful energy output to the total energy input - or the percentage of the work input that is converted to work output.






9. The measure of resistance to heat flow






10. 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






11. 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






12. The opposition that a device or material offers to the flow of direct current






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






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






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






16. 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






17. A type of system that uses circulating pumps and fans to collect and distribute heat.






18. A subset of a sample space






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






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






21. A resource that can be replaced when needed






22. 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.






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






24. An energy source that will never run out






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


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


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






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






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






30. 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






31. 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.






32. The collection and analysis of numerical data in large quantities






33. The use of gas flowing under pressure to transmit power from one location to another.






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






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






36. The loss of the load- bearing ability of a material under repeated load application - as opposed to a single load






37. Stages a product goes through from concept and use to eventual withdrawal from the market place.






38. The contact of a relay that is open when the coil is de- energized






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






40. Pressure exerted by a confined fluid acts undiminished equally in all directions


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






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






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






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






45. The amount or quantity of something






46. Categorical data graph






47. The type of charge an atomic particle has






48. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose






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






50. Any device that controls - either automatically or manually - the flow of a fluid.
