STRUCTURES

STRUCTURES

1. Artificials: are the human made structures.

   • LOADS: force that acts ina structure
     • for example: the wind, the weight...
     • STRESSES : effects that loads cause in a structure
       • TRACTION: loads stretch the structure
       • COMPRESSION: load compress the structure
       • SHEAR: load shear the structure
       • TORSION: load twist the structure
       • BENDING : load bend the structure

2. Naturals: are structures created by nature.

3. FORCES are anything that can produce changes in a body

   • for example: when you press dow, when you push,and when you drop things.

4. Structural condicions

   • RIGIDITY: capacity to become deformes but the deformation must no prevent it from fulfilling is function
   • STABILITY: is the capacity of remain upright and not tip over
   • RESISTANCE: is the capacity to bear the stresses without breaking
