The elasticity of the solid will return to its original shape upon loss of force. Everything when acquiring a style, then will undergo a change. Changes in shape and size, whether solid, liquid, or gas.
There are some objects when gaining a force will return to its original shape after removing the force. But there is also a change into a new form. This change in shape has to do with the elasticity of the object.
Elasticity is a property of an object. It tends to return the object to its original state. After experiencing a change in shape, there is the influence of external forces.
Definition of Elasticity of Solids
Elasticity or elasticity is the ability of an object to return to its original shape. After obtaining the outer style, then eliminate the style. While the ability of a solid object to return to its initial form.
After styling the object and removing it. It is called the elasticity of solids. Launching Wikipedia, elasticity is the tendency of solid materials to return to their original shape after deformation of the object.
A solid object will deform when a force is applied to it. In some objects that have elasticity or are elastic, then call it an elastic object.
As well as rubber bands, springs, and metal plates. While plastic objects are some objects that do not have elasticity or do not return to their original shape. Like clay and plasticine or toy wax.
For the manufacture of plastic objects are synthetic materials. Then heat the objects or process them chemically. This is so that it becomes strong and eventually does not become a plastic object anymore.
Deformation
The elasticity of solids when they get a force, will also experience deformation. Deformation is a change in size or shape. That’s because it acquires a force, the molecules of the object react.
It even exerts its force to inhibit deformation. The external force is the object that acquires a force, while the internal force is the reaction of the molecules. When removing the outer force, the inner force tends to restore shape.
In addition, it also restores the size of the object to its initial state. Many everyday materials have elastic properties, but they are only temporary. When gaining force on these materials will not return to their original shape.
This condition as the limit of elasticity of solids has been exceeded. When compared to liquids, solids are harder and heavier. Some solid molecules are tightly packed together, so the bonds are relatively strong.
This is the reason why solids are relatively not easily destroyed. As for splitting wood requires other tools and great force.
Every effort to separate the molecules of the solid. Like the existence of attraction or pressure, will always be resisted by the attractive forces between the molecules of the solid.
Magnitude of Elasticity
Quantities have a relationship with the elastic properties of solids. The following are some quantities of physical elasticity.
Voltage
Stress is the amount of force acting on an object with a certain cross-sectional area. Even showing the strength of the force causes a change in the shape of an object.
Stretches
Strain is the relative change in the size of an object when subjected to stress. To calculate strain by comparing the increase in the length of an object to its initial length. Strain is a measure of how far an object is deformed.
Stress gets the material from the outside, while strain is the material’s response to stress. In the elastic region of solids, the stress is directly proportional to the strain.
Compression
Compression is almost similar to stretching. However, when the stretch occurs, the force of attraction pushes the molecules of the object pushed out. While compression occurs due to the force that makes the molecules of the object go inside.
Modulus of Elasticity (Modulus Young)
The young modulus is the magnitude of the force that works on a certain cross -sectional area. It’s to stretch an object. Young’s modulus as a comparison between tension and strain on an object.
Young’s modulus value displays the level of elasticity of the object. The larger the value, the greater the stress required to stretch the object.
In measuring Young’s modulus using acoustic waves. That’s because the speed of the road depends on Young’s modulus.
All objects when getting a force, it will experience a change in shape and size. Even in the elasticity of solids, it returns to its original shape when the force is lost.
