not break when
reciving a sudden
shock. (glass)
- Elasticity
- materia that deforms
when a force is
applied. (rubber)

- Stress
- Tension
- when an object is pulled with
two forces, acting in diferent
directions. (cables)
- Compression
- when an object is pushed
with two diferent forces
acting in opposite direction.
(columns)
- Flexion
- an object, one in
under compression
and the other
under tension.
(beams)
- Torision
- when an object is
twisted by the action
of two diferent
forces.
- Shear (cisallament)
- two opposite forces
act in the same part of
the object, trying to
cut it
