Unit 4. Strucutres

1. loads

   • stress
     • conditions
       • rigidity
         • to deform as less as possible
       • stability
         • to remain upright an not tip over
       • resistence
         • to bear loads without breaking
     • Types of stresses
       • traction
       • compresion
       • bending
       • torsion
       • cutting
   • permanent loads
   • variable loads

2. Structures

   • massive
   • vaulted
   • frame or lattice
