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






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






3. The total pressure exerted on a system - including atmospheric pressure.






4. A body subjected to a push.






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






6. The use of a fluid (liquid or gas) to transmit power from one location to another.






7. The result of an experiment






8. The rate of change of velocity with respect to time.






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






10. The reason for which something is done or for which something exists.






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






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






13. The flow of electrical power or charge.






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






15. The unit of potential difference symbolized as V






16. A truss that lies in a single plane often used to support roofs and bridges






17. 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.






18. A circuit in which all parts are connected end to end to provide a single path of current






19. Frequency distribution graph






20. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit






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






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






23. The geometric center of an area.






24. A rough drawing representing the main features of an object or scene and often made as a preliminary study.






25. A switch that can provide variable motion control






26. The turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from the force.






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






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






29. The information produced by a computer






30. A body subjected to pull.






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






32. A resource that can be replaced when needed






33. 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.






34. Every body or particle continues at a state of rest or uniform motion in a straight line - unless it is compelled to change that state by forces acting upon it.

35. The transfer of energy by electromagnetic waves






36. A subset of a sample space






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






38. The process of creating an object by adding small pieces or layers together to make a final product






39. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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

41. A group of machined or handmade parts that fit together to form a self- contained unit.






42. The calculated likelihood that a given event will occur






43. An air pump that compresses air into a receiver tank.






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






45. The state when objects are not yet in motion






46. A support that prevents translation and rotation in a beam.






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






48. The measure of resistance to heat flow






49. Used to transport fluid in a circuit






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