Flexibility of Snowboards

    Flexibility is very important for snowboards to operate properly.  Without it, boards would break, users would crash, and not nearly as many tricks would be possible.  The flexibility of a snowboard is due to the materials that make one up.  There are many layers of different materials that make up a snowboard.  At the core of a board is wood or foam.  Glued to it is rubber foil and fiberglass.  On top of that there are metal edges, plastic bases, steel inserts for the bindings, and finally the top sheet with graphics.  Every material in a snowboard has its purpose for delivering the intended experience.  The flexibility of a material can be represented by k=F/δ, where k is the materials stiffness, F is the force applied to the material, and δ is the displacement caused by the force.  With constant force, the more a material is displaced, the less stiff it is.  Therefore, it has more flexibility.
