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.

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






25. The recognized accreditor for college and university programs in applied science - computing - engineering - and technology.






26. 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






27. The amount or quantity of something






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






29. The use of quality control techniques associated with a process.






30. A system that links electricity produced in power stations to deliver it to where it is needed






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






32. 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






33. A type of pressure control valve that limits the maximum pressure in a hydraulic or pneumatic circuit.






34. An energy source that will never run out






35. Individual fuel cells that are combined in series.






36. The resultant of a system of force is the vector sum of all forces.






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






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






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






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






41. 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






42. The use of a liquid flowing under pressure to transmit power from one location to another






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






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






45. 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






46. The absolute pressure of a confined gas is proportional to its temperature - provided its volume stays constant

47. Listing of a data values along with their corresoponding frequencies.






48. Change in length of an object in some direction per unit






49. Nominal stress developed in a material at rupture. Not necessarily equal to ultimate strength. Since necking is not taken into account in determining rupture strength - seldom indicates true stress at rupture






50. Measure of data scatter
