The coefficient of elasticity (CE) is a measurement of the strength of an object or substance. It is calculated by dividing the stress (elastic parameter) by the displacement (elastic capacity).
The stress elastic parameter or the “stiffness” of an object or substance is the force generated by compressing a part of an object or substance in a given direction. The displacement elastic capacity is the force generated by stretching the same part of an object or substance in a given direction.
The stress elasticity of a material is a measure of how easily a force can be transmitted through the material. The stiffness of an object or substance is the force needed to stretch the same part of an object or substance in a given direction.
The first question I usually ask about something is, “what is the coefficient of elasticity?” Well, the coefficient of elasticity is the ratio of force to displacement. The problem with this question is that the actual coefficient of elasticity is a function of how the object or substance is made (the material). In a nutshell, the coefficient of elasticity is the ratio of force to displacement and will change depending on the quality of the material.
The term elasticity is also a useful term to understand how the physical properties of things change.
The most important factor when talking about materials is hardness. Hardness is the ability of a material to crack and crack and crack. As we know, hard materials have more of a tendency to crack. In the next few paragraphs, we will go over the various ways in which we can measure hardness.
How do you measure hardness? Hardness is measured by force. We can’t measure force by our hand, but we can measure force by a force sensitive device. With a force sensor we can measure the amount of force required to break something. The amount of force required to break a substance is called the “coefficient of elasticity.” A substance that has a larger coefficient of elasticity is more like a rubber band than a tough substance.
This is a big problem, a big problem. Because we know it’s a rubber band, we need to know if it’s a rubber band because it’s going to break or an elastic band because it’s going to break. So we measure force by force, and if we measure force by force we do it with a high degree of accuracy. If we measure force by force we measure force by the force that is being measured, which is the force that we need to break.
The problem is that, in practice, these two forces are not equal. What is this force that we need to break? The force when a rubber band is stretched or the force when a rubber band is compressed. If we take the difference between these two forces we get the elastic properties of the rubber band. So the more stretch, the more elastic. And if we take the difference between the two forces we get the force that is being measured.
