Force Of Elastic Band

When an elastic material is stretched or compressed it exerts elastic force.

Force of elastic band.

A rubber band s elasticity is explained by looking at rubber elasticity and thermodynamics. 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. It takes more force to stretch them the farther you pull. Or you could say the force a band pulls back is proportional to the stretch.

Both springs and rubber bands have a special property. In this case the linear function fitting the straight part of the data gives a spring constant of 17 38 n m. There are several molecular mechanisms that work together to produce the elastic force. Understanding the physics of elasticity requires a knowledge of advanced mathematics chemistry and statistical physics particularly the concept of entropy.

This is in contrast to plasticity in which. 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. This force increases the more the material is stretched or compressed. Elasticity is the ability of a material to return to its original shape after being stretched or compressed.

If the material is elastic the object will return to its initial shape and size after removal. This means you can effectively get stronger without. 99 17 99 17. In rubber the elastic force is due to the thermal interactions of the molecules within the material.

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. Solid objects will deform when adequate loads are applied to them. Elastic force has many uses from hair scrunchies to bed springs. After you get the rubber band stretched just a little bit it is very spring like.
