STRUCTURES

1. A STRUCTURE is a set of elements of an object that allow it to maintain its shape and size without deforming when forces act on it

   • ARTIFICIAL structures
     • are all manmade.
   • structures NATURALS
     • the queleton of the animals, the trunk of a tree, the nests of the birds
   • The function of a structure is: Support weights , resist external forces , maintain the form ,Protecting objects
     • LOADS AND EFFORTS As we have commented the structures are subject to external forces that we will call CHARGES. These loads can be of two types
       • DYNAMIC LOADS
       • STATIC LOAD
       • These loads cause a series of EFFORTS to appear in the structure, which must be supported without deformation or breakage. There are 5 types of EFFORCES depending on the load
         • TRACTIVE EFFORT
         • Effort. COMPRESSION
         • Effort. FLOWERING
         • Effort. TORSION
         • Let's see how each effort works.
           • TRACTION
           • COMPRESSION
           • FLEXION
           • TORSION
           • SHEARING OR CUTTING
