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






2. A form of energy that travels through space as waves.






3. A step- by- step procedure for solving a problem or accomplishing some end - especially by a computer.






4. Values that represent a measurable quantity






5. 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






6. Distance between adjacent threads in a screw.






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






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






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






10. The state when objects are not yet in motion






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






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






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






14. A conductor wrapped around an iron core. The two ends of the conductor are attached to a power source. When current passes through the conductor - the iron core becomes magnetized.






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






16. A person who designs any of a variety of things. This usually implies the task of creating drawings or in some way using visual cues to organize work.






17. 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






18. 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.






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






20. Changes one form of power to another






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

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






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






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






25. Frequency distribution graph






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






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






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

29. A major or minor change in the design of an item - effected in order to correct a deficiency - to facilitate production - or to improve operational effectiveness.






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






31. Categorical data graph percentage






32. A circular toothed object used to transfer rotary motion and torque through interlocking teeth






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






34. The result of an experiment






35. Ratio of distance traveled by the applied effort and resistance force within a system.






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






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. 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






39. Values that possess names or labels






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






41. A structure or body which is over- constrained such that there are more unknown supports than there are equations of static equilibrium.






42. A cylinder that can act under pressure in both directions (extend and retract) to move a load.






43. 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.






44. Amount of difference between a value and the mean.






45. Absolute temperature scale






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






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






48. Bell- shaped probability distribution






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






50. The calculated likelihood that a given event will occur
