Aerospace Materials And Properties

Subject : engineering
Instructions:
  • Answer 21 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. A force with its resultant passing through the centroid of a particular section and being perpendicular to the plane of the section. A force in a direction parallel to the long axis of the structure.






2. The geometric center of an area.






3. A material made of multiple layers of fibers held together with a matrix.






4. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic






5. Condition caused by collapse - break - or bending - so that a structure or structural element can no longer fulfill its purpose.






6. A mathematical property of a cross section that is concerned with a surface area and how that area is distributed about a centroidal axis.






7. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus.






8. 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.






9. Temporary loss of strength and energy resulting from hard physical or mental work






10. 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.






11. The ability of a material to resist deflection or stretching.






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






13. The force acting across a unit area in a solid material resisting the seperation - compacting - or sliding that tends to be induced by external force.






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






15. Change in the length of an object in some direction per unit.






16. The amount of plasticity that procedes failure.






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






18. The way a material responds to specific machining techniques.






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






20. The condition of a string - wire - or rod that is stretched between two points.






21. A projection used for strength or for attaching to another object
