structures

1. A structure is a collection of elements arranged in an optimun way to supot a boody or an object

   • mass structures
   • truss stuctures
   • frame structures
   • suspended structures

2. forces, streses and strenght

   • force
     • is an influence that can deform the structure
   • stresses
     • are the physical demand that body or objectmust withstand
   • strength
     • is its hability to withstand external forces

3. elements than increase stability

   • centre if gravity
   • equilibrium

4. conditions for strong stuctures

   • rigidity
   • equilibrium
   • tipes of stress
     • compresion
     • tension
     • shear
     • torsion
     • bending
