STRUCTURES

1. What is a structure?

   • Is anything that support an object or a load

2. What efforts can support a structure?

   • Traction
     • is an effort that support a structure when is trip of other external forces
     • Compression
       • compression means reduction of volume when we compress a structure
       • Bending
         • shape or force (something straight) into a curve or angle.
         • Torsion
           • is the twisting of an object due to an applied torque
           • Cutting
             • is the ability of cut a thing in two parts or more

3. Fuctions of a structure

   • support weight
     • resist external forces
       • overcome obstacles
         • protection
           • close empty spaces

4. Types of structures

   • Natural structures
     • Artificial structures

5. A structure can have:

   • Resistence
     • Rigity
       • Stability

6. Gravity

   • A structure has to have a point of gravity
     • We take the higher point and we have to throw a straight line in the middle of the basis
   • is all that are attract from the Earth´s centre
