STRUCTURES
TYPES OF FORCES
Flexion: A body is subjected to flexion when a force acting in it acts on it perpendicular to its axis, which tends to bend it. 
Shear: A body is subject to twisting when two act on it pairs of opposite forces in the opposite direction, that is, that usually its sections tend to take one movement of rotation in opposite sense of the others.
Compression: A body is subject to compression when two equal forces act on him towards international and in the opposite sense.
Torsion: Let's say a body is subject to bonding, which is subjected to compression being its length very large and its small cross section. This is it the case of pillars.
Tension: A body is subjected to traction when two forces act on it outwards and in opposite directions, tending to increase its length.
TYPES OF STRUCTURES
Massive: They are structures in which a large concentration of material predominates. They are characterized by being stable and very heavy. Examples are the pyramids, temples, dams, walls.
-
Triangulated: Triangular structures are formed by joining many triangles that build flat or spatial networks. Each triangle is subjected to its own tensile and compressive stresses.
Frame: They are made of a set of wooden, steel or concrete profiles that intersect with each other. The structural elements are the beams, pillars or columns and the foundation
