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






2. An electromagnetically operated switching device.






3. 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






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






5. Energy derived from sources that do not use up natural resources or harm the environment






6. The state when objects are not yet in motion






7. The type of charge an atomic particle has






8. A body subjected to pull.






9. A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen or stiffen it.






10. A support that only prevents a beam from translating in one direction.






11. The geometric center of an area.






12. A diagram used to isolate a body from its environment - showing all external forces acting upon it.






13. A switch that can provide variable motion control






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






15. A truss composed of triangles - which will retain its shape even when removed from supports.






16. 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.






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






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






19. 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






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






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






22. A rigid bar used to exert a pressure or sustain a weight at one point of its length by the application of a force at a second and turning at a third on a fulcrum.






23. 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.






24. Not having fixed limits; unrestricted; broad






25. 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.






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






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






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






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






30. A device used to convert fluid power into mechanical power in the form of linear motion.






31. Maximum stress that a material will withstand without permanent deformation






32. 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.






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






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






35. The measure of resistance to heat flow






36. The probability that a component part - equipment - or system will satisfactorily perform its intended function under given circumstances - such as environmental conditions - limitations as to operating time - and frequency and thoroughness of mainte






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






38. Crude or processed material that can be converted by manufacture - processing - or combination into a new and useful product; something with a potential for improvement - development - or elaboration






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






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






41. 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.

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






43. A limit to a design process. Constraints may be such things as appearance - funding - space - materials - and human capabilities






44. The ability to get answers to questions through a conscious - organized process. The answers are usually - but not necessarily - quantitative






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






46. A plate or bracket for strengthening an angle in framework.






47. 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.






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






49. The probability of satisfactory operation of the product in a given environment over a specified time interval.






50. An activity with observable results
