Elastic Modulus Of Rubber Band

Silicones are polymers with a si o si backbone.

Elastic modulus of rubber band.

Gruand méca sarl cy for his redaction. In other words it is how easily it is bended or stretched. This can be repeated many times with no apparent degradation to the rubber. The rubber he used had high modulus.

There are different types depending on functional groups in the structure and curing mechanisms. Thomas young his british fellow countryman will leave his name associated to this linear behavior of many materials. 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. 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. Which response is correct with additional information which is now in a question comment. Where stress is the force causing the deformation divided by.

Key properties include thermal stability chemical stability electrical insulation and low toxicity. It is dependent upon temperature and pressure however. Main applications are flexible seals o rings etc. 1 because the rubber band is expected to stretch more fo.

Young s modulus is also known as tensile modulus elastic modulus and modulus of elasticity measure of elasticity. 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. The young s modulus or elastic modulus is in essence the stiffness of a material. A rubber band would have a low tensile set percentage.

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. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. 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. The question was which has a greater young s modulus a steel wire or a rubber band and why.

Young modulus for rubber. It is resilient and yet exhibits internal damping. The young s modulus of a material is a fundamental property of every material that cannot be changed. Elongation is proportional to applied strength.

Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule. A stiffer material will have a higher elastic modulus.
