Rigidity

Back

Physical stiffness is associated with difficulty in movement or a reduction in elasticity.

Latin is where we find the etymological origin of the word that we are going to analyze exhaustively below. Specifically, we can establish that it comes from the verb rigere , which had two clear meanings. Thus, on the one hand, it was synonymous with being stiff, with not being able to bend; and on the other hand, it was equivalent to being frozen with cold.

Rigidity is known as something that has the particularity of being rigid (that is, it cannot be bent or that is rigorous, inflexible and severe). To give examples of use: “You have to do something to avoid the rigidity of your spine,” “My father was always characterized by his rigidity.”

Physical rigidity

In the physical sense, the idea of ​​rigidity is associated with the lack of elasticity or ability to move . Relaxation exercises, stretching and good posture are key to avoiding stiffness. In this way, it is possible to rest better and achieve better performance in physical or athletic activities.

Sometimes, this stiffness can occur for reasons as simple as having spent many hours on the computer, a poor sleeping position or even exposure to cold and air currents. In order to put an end to the stiffness caused by these or other similar reasons, there are a series of tricks or home remedies.

Among these remedies we can find applying hot compresses, making use of so-called orthopedic pillows, carrying out relaxation or meditation exercises, including pineapple in the diet, taking hot showers and letting it fall directly on the skin. affected area or take some turmeric infusions.

However, there are many other home remedies to alleviate this pain and even medical treatments when the situation is serious.

Conduct

The rigidity of a behavior is given by the subject's attachment to the rules.

severe behavior

Rigidity, on the other hand, can be manifested through severe conduct or impeccable behavior in accordance with ethical and moral standards.

A rigid man, in this context, does not allow himself any slip or behavior that could be objected to on a social level.

Rigidity in engineering

For engineering , the rigidity of something is evidenced by the ability of a structural part or a solid material to withstand stress without deformation or displacement . The quantification of stiffness against various load configurations can be expressed through stiffness coefficients, which are physical quantities.

It is also worth mentioning that stiffness is usually calculated by identifying the ratio that arises from comparing the force that has been applied and the displacement that occurred as a result of the effects of said force . The axial rigidity of a beam or bar is known as the ability to withstand stretching or compaction attempts as a result of the force that has been applied based on its axis.

The flexural stiffness of a bar, on the other hand, describes the link between the bending moment that was applied at one end and the angle that has been rotated by said end when undergoing deformation.
