Tenacity is a feminine noun from the Latin term tenax, which means the quality of the which is tenacious, that is, that it has great cohesion, which is firm, viscous, very adherent, constant and persistent.
Tenacity is a concept within the Physics, which describes a mechanical property of some materials.
Regarding the etymology, the word tenacity is related to the verb to hold or to take, which can to qualify a persistent person, with fixed ideas, in such a way that it can sometimes annoy or annoy the others.
In a figurative sense, the word tenacity is used to describe the attitude of a stubborn or persistent person who does not give up on a project or idea. Ex: He is an example of tenacity, because he never gave up on his dream, even when everyone tried to discourage him.
Material tenacity
In the field of Physics, tenacity (whose unit is J/m3) consists of a mechanical property of metals, of absorption of energy, which indicates its resistance, when a traction force is applied to it, which can lead to deformation or even break. In objects with high tenacity, the molecules have great cohesion between them.
It is a mechanical property such as ductility (ability of some materials to undergo deformation without breaking) and the resilience(Ability to absorb mechanical energy when subjected to stressful situations, such as ruptures).
In some objects such as concrete plates, for example, metal beams are introduced in order to increase their tenacity.
