Structures

1. A structure is formed by a group of elements of a thing wich gives force to preserve its size and shape without collapse when forces act on it

   • Natural structures
     • natural structures are those that are form by nature
       • some examples are:
         • The skeleton
           • The structures supports charges,these loads can be:
             • Static loads
               • The static loads are those that stay always in the structure,some examples are:
                 • beams
                 • cement
                 • bricks
                   • The loads causes a series of efforts,the 5 most important are:
                     • Flexion
                       • A estructure is composed by some elements,the most important are:
                         • Foundation
                           • All structures must be :
                             • Stable
                               • The stability is the point in a structure where all the weigth is concentrated
                             • Resistant
                               • Resistance is the way in wich a structure is built to be stronger and thus withstand well the external forces that act on it.
                                 • Triangulation is the most used technique in wich the structure forms a triangle shape,it is used the most because the triangle distributes the weigth
                         • Pilar or colum
                         • Tirante
                         • Square
                         • Viga
                     • Torsion
                     • Cuting
                     • Compression
                     • Traction
             • Dynamic loads
               • The dynamic loads are those that don't exist always in teh structure,some examples are:
                 • wind
                 • people
                 • rain
         • A turtle shell
         • A coral reef
   • Artificial structures
     • Artificial structures are those made by the human
       • Some examples are:
         • The pyramids
         • A car
         • A mobile phone
   • The functions of a structure are:
     • Protecting objects
     • Support weigths
     • To resists external forces
     • To mantein the form
