Force Of Elastic Band

After you get the rubber band stretched just a little bit it is very spring like.

Force of elastic band. If the material is elastic the object will return to its initial shape and size after removal. Rubber polymers chain together to form an entropic spring and is a standard example of an entropic force. 99 17 99 17. Elastic potential energy measured in the unit joules is equal to multiplied by the stretch length x squared multiplied by the spring constant k the spring constant is different for.

In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. A rubber band s elasticity is explained by looking at rubber elasticity and thermodynamics. Elastic force has many uses from hair scrunchies to bed springs. Solid objects will deform when adequate loads are applied to them.

Or you could say the force a band pulls back is proportional to the stretch. In rubber the elastic force is due to the thermal interactions of the molecules within the material. This is why an elastic band gets longer the harder you pull it and why a rubber ball squashes more the harder you. By stretching against force in pushing or pulling exercises these rubbery tubes or flat loops add load both on the action and on the return.

Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy. Both springs and rubber bands have a special property. In general the greater the force exerted the greater the amount of deformation. Elasticity is the ability of a material to return to its original shape after being stretched or compressed.

In physics and materials science elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. There are several molecular mechanisms that work together to produce the elastic force. This means you can effectively get stronger without. This is in contrast to plasticity in which.

It takes more force to stretch them the farther you pull.
