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. 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






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






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






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






5. A systematic problem- solving strategy - with criteria and constraints - used to develop many possible solutions to solve a problem






6. Two different sized circular objects that are attached together and turn as one.






7. An activity with observable results






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






9. 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.






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






11. The absolute value of a number






12. The transfer of energy by electromagnetic waves






13. An external force applied to an object.






14. Arithmetic average






15. A substance that tapers to a thin edge and is used for splitting - raising heavy bodies - or for tightening by being driven into something.






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






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






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






20. Something made up of interdependent parts in a definite pattern of organization - such as trusses - frames - or machines.






21. A valve that allows flow in one direction but prevents flow in the opposite direction.






22. 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.






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






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






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






26. A statsitical measurement of variability






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






28. Frequency distribution graph






29. A resource that can be replaced when needed






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






31. Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units - each a relatively light and simple molecule






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






33. A profession for which one trains and which is undertaken as a permanent calling.






34. The measure of resistance to heat flow






35. The result of an experiment






36. An organization that works to develop and enforce regulations that implement environmental laws enacted by Congress






37. A fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work






38. The collection - evaluation - and interpretation of data






39. 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






40. Not having fixed limits; unrestricted; broad






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






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






43. A part or element of a larger whole






44. A device that responds to a physical stimulus






45. A condition where there are no net external forces acting upon a particle or rigid body and the body remains at rest or continues at a constant velocity.






46. The unit of potential difference symbolized as V






47. Sometimes referred to as tensile strength; determined by measuring the maximum load a material specimen can carry when in the shape of a rectangular bar or cylindrical can






48. The measure of resistance to heat flow






49. The unit of electric resistance in the meter- kilogram- second system of units. Symbolized as O






50. The state when objects are not yet in motion
