Elastic Modulus Of Rubber Band

It is dependent upon temperature and pressure however.

Elastic modulus of rubber band. In other words it is how easily it is bended or stretched. Gruand méca sarl cy for his redaction. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule.

Elongation is proportional to applied strength. 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. It is resilient and yet exhibits internal damping. The elastic modulus of an object is defined as the slope of its stress strain curve in the elastic deformation region.

Rubber elasticity refers to a property of crosslinked rubber. The modulus of elasticity also known as the elastic modulus the tensile modulus or young s modulus defined as the slope of its stress strain curve in the elastic deformation region. The door was hard to close because the. Which response is correct with additional information which is now in a question comment.

A stiffer material will have a higher elastic modulus. Main applications are flexible seals o rings etc. Young s modulus is also known as tensile modulus elastic modulus and modulus of elasticity measure of elasticity. The question was which has a greater young s modulus a steel wire or a rubber band and why.

Rubber has a low modulus of elasticity and is capable of sustaining a deformation of as much as 1000 percent after such deformation it quickly and forcibly retracts to its original dimensions. This can be repeated many times with no apparent degradation to the rubber. There are different types depending on functional groups in the structure and curing mechanisms. A rubber band would have a low tensile set percentage.

After stretched it relaxes close to if not exactly to its original length. Where stress is the force causing the deformation divided by. You could still graph the stress strain relationship. I have a feeling that the stress strain behavior of the rubber band will be nonlinear so the concept of young s modulus might be irrelevant.

Key properties include thermal stability chemical stability electrical insulation and low toxicity. Silicones are polymers with a si o si backbone. Young modulus for rubber. 1 because the rubber band is expected to stretch more fo.

An elastic modulus also known as modulus of elasticity is a quantity that measures an object or substance s resistance to being deformed elastically i e non permanently when a stress is applied to it. The young s modulus or elastic modulus is in essence the stiffness of a material.
