The glass can be considered as been vitreo. The great difference between glasses and the other materials is high viscosity above of the fusing point. It is characterized by a physical solid behavior with liquid structure, that is, it is a intermediario point between I eliminate it and the solido one and does not possess symmetry. Its moleculas does not hold as I eliminate, that relatively they are joined and nor as solidos that extremely they are joined.  \nI wait that voce has understood.  \nIt forgives for possiveis errors of gramatica, text orininalmente in Portuguese.    \n\nKlarc - student of Engineering of Producão - Brazil

well, others might have told you it is pressure, and actually even i would have gone for it!\nbut since you have mentioned in particular on a fluid, then this ratio can also be called as Bulk's modulus(though this applies even to solids)\nit can also be the coeff of viscosity taken velocity gradient times\nthere can be various other depictions also

Its better to get a design engineering guide from one of the plastic raw material suppliers as modifying the melt flow index would change many other properties also. A manufacturer rather than a distributor would probably provide you the information more readily.

It is sometimes said that glass in very old churches is thicker at the bottom than at the top because glass is a liquid, and so over several centuries it has flowed towards the bottom.  This is not true.  In Mediaeval times panes of glass were often made by the Crown glass process.  A lump of molten glass was rolled, blown, expanded, flattened and finally spun into a disc before being cut into panes.  The sheets were thicker towards the edge of the disc and were usually installed with the heavier side at the bottom.  Other techniques of forming glass panes have been used but it is only the relatively recent float glass processes which have produced good quality flat sheets of glass.\n\nTo answer the question "Is glass liquid or solid?" we have to understand its thermodynamic and material properties.\n\nThermodynamics of glass\n\nThere is still much about the molecular physics and thermodynamics of glass that is not well understood, but we can give a general account of what is thought to be the case.\n\nMany solids have a crystalline structure on microscopic scales.  The molecules are arranged in a regular lattice.  As the solid is heated the molecules vibrate about their position in the lattice until, at the melting point, the crystal breaks down and the molecules start to flow.  There is a sharp distinction between the solid and the liquid state, that is separated by a first order phase transition, i.e. a discontinuous change in the properties of the material such as density.  Freezing is marked by a release of heat known as the heat of fusion. \n...\nConclusion\n\nThere is no clear answer to the question "Is glass solid or liquid?".  In terms of molecular dynamics and thermodynamics it is possible to justify various different views that it is a highly viscous liquid, an amorphous solid, or simply that glass is another state of matter which is neither liquid nor solid.  The difference is semantic.  In terms of its material properties we can do little better.  There is no clear definition of the distinction between solids and highly viscous liquids.  All such phases or states of matter are idealisations of real material properties.  Nevertheless, from a more common sense point of view, glass should be considered a solid since it is rigid according to every day experience.  The use of the term "supercooled liquid" to describe glass still persists, but is considered by many to be an unfortunate misnomer that should be avoided.  In any case, claims that glass panes in old windows have deformed due to glass flow have never been substantiated.  Examples of Roman glassware and calculations based on measurements of glass visco-properties indicate that these claims cannot be true.  The observed features are more easily explained as a result of the imperfect methods used to make glass window panes before the float glass process was invented.

The E modulus for balsa is 5GPa (giga pascals).\nwhere 1 Pascal is 1 N/m2 and from here 1MPa is 1million time greater or 1N/mm2 and one GPa=1000MPa

You can find it using the general bending formula as related to torsion (twisting) rather than bending.\n\nT/j = G/Theta x L = Shear stess/Radius\n \nThe folowing link explains much better than I can.\n\nhttp://www.freestudy.co.uk/c105.htm

Glassy solids are considered amorphous solids.  An amorphous solid is a solid in which there is no long-range order of the positions of the atoms.  Common window glass is an amorphous ceramic.\n\nPerhaps you meant what is the difference between "rubbery" and "glassy" states?  The temperature at which there is a  transition between the glassy and rubbery states is called the glass transition temperature.  An amorphous material in the rubbery state is flexible.  In the glassy state, it is brittle.

depending on how big the glass is!!! do the math!!!

If you are talking about regular soda-lime glass, the reason why it is brittle is because its molecular structure resembles that of a liquid.  HOWEVER, it does not have a liquid structure.  Glass is composed of tetrahedral crystals.  That these crystals did not achieve regular, repeating crystalline structure does not mean glass is a permanent liquid.  My Glass Ceramics prof nearly shot me for saying that in class one day.\n\nBut that's exactly it:  Glass is brittle because it does not have good large-area orderly crystalline structure.  If it did, it would be like sheetmetal steel, where it dents and deforms instead of shattering.\n\nI would like to point out something else though:  The strongest fiber ever tested was a glass fiber drawn and tested in an inert atmosphere.  Also, you can take a glass fiber by the ends and bend it into a circle, much like any metal wire.  Hence it is elastic.  BUT if you touch that same fiber in several places, then try to bend it again it will shatter in your hands.
