Structures

Structures

1. Is the set of elements of an object or body that support external actions so that the body or object doesn't deform or break

   • Natural Structures
     • Aren't made by people, they are made by nature
   • Human-made structures
     • Are made by people

2. Forces, loads and stresses

   • Gravity: the force wich attracts a body towards the centre of the earth
   • Wind: the force wich might move trees, buildings or mills
   • Pressure: continous physical force applied on or against an object by something in contact with it
   • Forces
     • Is anything that can deform a body or make it move or stop
       • External Forces: Act on the structures from outside it, like wind
       • Internal Forces: Relate with a material's properties and their capability to resist external actions
   • Loads
     • Forces that act on a specific structure
       • Fixed or Permanent Loads: These don't change over time
       • Variable Loads: These sometimes affect the object and sometimes they don't.
   • Stress
     • Is the cuantity of force that an object resists during deformation
       • Mechanical Stresses
         • Tension
         • Compression
         • Bending
         • Torsion
         • Shearing or Cutting
