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. The measure of resistance to heat flow






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

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






5. Individual fuel cells that are combined in series.






6. Mechanical property of a material that indicates the ability of the material to handle overloading before it fractures






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






8. A toothed wheel whose teeth engage the links of a chain.






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






10. 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






11. A type of pneumatic pressure control valve that controls the maximum pressure in a branch of a circuit.






12. The connection points of members of a truss






13. An inclined plane wrapped around a cylinder - forming the path and pitch.






14. A vector quantity giving the straight- line distance and direction from an initial position to a final position.






15. A group technique for solving problems - generating ideas - stimulating creative thinking - etc. - by unrestrained spontaneous participation in discussion






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






17. The type of charge an atomic particle has






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






19. The change of motion of the body is proportional to the net force imposed on the body and is in the direction of the net force.

20. 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.






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






22. Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials






23. Numbers or information describing some characteristic.






24. A gear positioned between the driver and the driven gear used to change rotational direction.






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






26. A series of usually metal links or rings connected to or fitted into one another and used to transmit motion and power within a sprocket system.






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






28. An electromagnetically operated switching device.






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






30. 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






31. A straight line that comes closest to the points on a scatter plot






32. Information fed into a data processing system or computer.






33. The state when objects are not yet in motion






34. Absolute temperature scale






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






36. The pressure exerted by the weight of the atmosphere above the point of measurement.






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






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






39. 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






40. Impeding effect exerted by one material object on another.






41. The value that occurs most frequently






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






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






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






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






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






47. 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.






48. The result of an experiment






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






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