Why Rubber Band Is Elastic

That is why rubber bands are elastic.

Why rubber band is elastic. Whether we re using them to hold back our hair organize papers or wrap around our pointer finger for a cheeky snapshot the elasticity of rubber bands allows them to perform many functions that we rely on every day especially our fruit cutting needs. A rubber band also known as an elastic band gum band or lacky band is a loop of rubber usually ring shaped and commonly used to hold multiple objects together the rubber band was patented in england on march 17 1845 by stephen perry. When a rubber band is allowed to release and return to its high entropy state of tangles and knots the elastic force that causes that contraction is considered an entropic force. The elastics allow for the jaw and bite alignment to occur and are the patient s responsibility as they are removable and replaceable.

This is why rubber bands are sometimes called elastic bands. A cock ring essentially keeps blood trapped in your erection making it bigger harder and sometimes more longer lasting. The rubber bands connect to small hooks on the bracket and put a small amount of pressure in a specific direction to improve your bite.

Most rubber bands are manufactured out of natural rubber or especially at larger sizes elastomer and are sold in a variety of sizes.

When you stretch a rubber band the work done is spent on ordering the polymer chains and it immediately appears as heat released. Clearly the entropic force acting on the polymers wants to resist being stretched so when we pull on a rubber band we are performing work on the material. Unlike the rigid materials which store the energy within them in the form of potential energy elastic polymers immediately release the energy in the form of thermal energy. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance.

It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length. What do you think will happen to the elasticity stretchiness of a rubber band when it is heated or cooled to various temperatures. Elastomers have played a key role in the development of new technologies in the. When you stretch the rubber the polymers start to elongate or stretch.

A photograph shows a new home invasion technique featuring rubber bands and door handles. Because these polymers are so long they can be thousands of molecules long they get tangled up in themselves.
