structures

1. types of stuctures

   • mass
   • truss
   • frame
   • suspended

2. forces, stresses and strenght

3. conditons for strong stuctures

   • equilibrium
     • esquilibrium stable : a chair
   • stability
     • table
   • rigid
     • brik

4. types of stress

   • tension
   • bending
   • torsion
   • shear
   • compression

5. stregthening elemements

   • center of gravity
   • stable

6. elements that increase rigidity

   • trussing (triangle)
   • brace
   • sections
   • stay cables
   • open sections
   • closed sections
   • diqgonal bars, braces and stays
