Concept in Definition ABC

The one that concerns us is a concept that is used to refer to various issues in our language.

Something or someone that is tough

Generally speaking, the word hardness refers to the quality of hard that presents a thing, an object or a person. Lack of softness, sensitivity, roughness, and excessive severity they are clear signs of the presence of hardness in whatever context, that is, in a material, in an object, in a person, among others.

Characteristics of tough-acting people

It is very common for the term to be applied in relation to individuals to precisely account for their rigor and severity when acting or think.

People who act or think harshly are difficult to convince, to make them change their position or to think about something. They tend to be more sullen and hostile and therefore do not accept those things that are contrary to their ideals.

In some contexts or activities, people who hold this profile are often demanded, more than anything when it comes to imposing order and

discipline in a group, something that of course with someone weak or lazy can not be achieved.

Now, the limits are not good for anything, for example, it is that although toughness will be required to make a group function in an orderly manner Nor can one go to the extreme because submission will not bring much benefit, but on the contrary, it will cause fear and even endurance.

Softness and tenderness are the two concepts that are opposed to this term and for example, they are used when you want to indicate the opposite of hardness.

Calluses in certain parts of the body

On the other hand, the term hardness is also used to designate the calluses that can appear in different parts of our body, it is nothing more than a hard layer of skin. The hardness turns out to be very frequent on the soles of the feet and many times its origin has to do with the bad footprint, by the use of uncomfortable shoes, among other issues.

"I went to the podiatrist to have the hardness removed from my heels because I could no longer walk".
These are precisely the professionals who take care of extracting the hardness of our feet through a methodology Special elements and elements that do not hurt and allow their total removal and the return of the softness of the skin.

Now, this does not imply that they disappear forever and do not reappear. Over time they come out again and it is necessary to return to the podiatrist to perform the treatment again.

Mineral resistance

While, at the request of Geology, is designated with the term of hardness to the resistance than a mineral will oppose being scratched by another. The difficulty that they present when it comes to being scratched.
So, in this area, toughness is a mechanical property of minerals.

The hardness of minerals is studied and determined through the so-called scale of Mohs.
This table indicates the hardest and least hard minerals, the hardest being diamonds and the softest being talc.

The aforementioned scale is widely used when making convenient objects in relation to the needs presented by consumers, especially when hardness is sought.

Likewise, there is talk of hardness in terms of the penetrability that a surface has and that will be the one on which the possibility of making marks on it will depend.

For example, due to this last question, the metallurgical industry uses an instrument known as durometer to measure hardness during penetration tests.

The aforementioned tests consist of the use of different types of tips and the application of different loads in order to be able to analyze the loads carried out. And then, with those tests in hand, the different scales will be established.

Once the hardness of a steel is determined, for example, a correlation can be made between that hardness that resulted, with the mechanical resistance.
The machines that carry out these measurements are of utmost importance in industrial activity.

Something difficult

And finally, the term is also widely used in ordinary language with a sense symbolic when wanting to refer to something difficult or complex. The competence presented an unusual hardness, we were almost left out.

That is to say, this sense of the word is usually applied to refer to those activities that are characterized by present obstacles or complications that make them not easy and therefore require a greater effort to be able to overcome them.
