Man has, since the early times, found out how instrumental elastic materials are. And today ' s man has prominent on this image and constantly finds ways to make more elastic materials to suit his everyday needs.
Elasticity refers to the property of an item to deform when load is convenient to it, and to return to its spontaneous cut when the load is pleased. Many of the everyday things you stare around you are elastic materials: rubber bands, sports balls, slingshots, bows, and uniform bungees!
From the earliest days, man organize out that certain objects would spring ' back to its embryonic shape if pressure to deform the something was removed.
At primeval, this sort of annoyed him since the most common things that showed this property were grisly parts which he ate. At last between inventing flames and creating the rotate, he hope, Hmm, conceivably I could account this for something.
In consequence was born the primitive elastic weight made of plug extirpate to hold stuff well-adjusted. As time passed by, man found out that these elastic strings made from animal gut could be used as a weapon. When a projectile was loaded in to these elastic strings, they were propelled through the air at great speeds. Thus was born the bow and arrow.
Rubber is one of the more popular elastic materials around. Many products derived from rubber are bounced around, stretched, and pounded and they come back to shape.
Because of this property, many people find diversified reasons to love rubber. If people were to use rigid materials, those objects would break, or get deformed. And for some objects deformity equates to unusability.
Rubber was used by the Early American Indians before Columbus even set foot on the Americas. They called the substance Caoutchouc, which comes from the word cahuhchu meaning weeping wood. This substance came from the sap of the rubber tree.
At first the westerners found out that this substance could be used to rub out pencil stains. Therefore, it was called rubber to commemorate its glorious ability to rub.
Other elastic materials have varied uses in today ' s world. Rubber is used for tires, elastic bands, and other bouncy ' objects. Coiled spring is used for suspensions, and spring - loaded applications. They are even used in variable sized sheathings.
The most common example of this is the condom. Elastic materials are commonly used on clothing to provide a comfortable fit on people. They are also useful in cases where you need watertight equipment.
Elastic materials are also handy in creating cushioning materials: tires, soles for shoes, for cars, for beddings and other uses. These applications require materials that will protect the user from sudden shock. Elastic materials absorb the energy and disperse them in a non - traumatic manner for cushions.
These materials are also used in sports. Insulated, elastic balls are integral to many sports because non - elastic balls would deform when used. Basketballs, volleyballs, and soccer balls have to be elastic to allow them to return to their normal shape after being subject to load and trauma.
There seems to be no sure hint that the use of elastic materials will abate. There will constantly be use for these sort of materials. As man steadily finds ways to make use of these wonders, he also steadily finds better ways to create more elastic materials.
