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.

22. Graphical representation of a material's mechanical properties






23. 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






24. A small circuit board that controls all the processing within a computer.






25. A systemized body of laws; a set of principles - as of ethics






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






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






28. A device for making - breaking - or changing the connections in an electrical circuit.






29. 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.






30. 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.






31. The amount or quantity of something






32. Test methods used to examine an object - material - or system causing permanent damage to its usefulness






33. 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






34. 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






35. A solid- state switching device.






36. 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.






37. A force that produces or tends to produce rotation or torsion.






38. 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.






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

45. A body subjected to a push.






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






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






48. Processes that remove material to change the size - shape - or surface of a part. There are two groups of separating processes: machining and shearing






49. An energy source that will never run out






50. The connection points of members of a truss
