Elastic Modulus Of Rubber Band

1 because the rubber band is expected to stretch more fo.

Elastic modulus of rubber band.

Young s modulus is also known as tensile modulus elastic modulus and modulus of elasticity measure of elasticity. 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. Young modulus for rubber. The question was which has a greater young s modulus a steel wire or a rubber band and why.

Where stress is the force causing the deformation divided by. A stiffer material will have a higher elastic modulus. 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. You could still graph the stress strain relationship.

Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule. Main applications are flexible seals o rings etc. Silicones are polymers with a si o si backbone. There are different types depending on functional groups in the structure and curing mechanisms.

Gruand méca sarl cy for his redaction. 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. In other words it is how easily it is bended or stretched. 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.

Key properties include thermal stability chemical stability electrical insulation and low toxicity. The rubber he used had high modulus. The elastic modulus of an object is defined as the slope of its stress strain curve in the elastic deformation region. Thomas young his british fellow countryman will leave his name associated to this linear behavior of many materials.

After stretched it relaxes close to if not exactly to its original length. It is dependent upon temperature and pressure however. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and. This can be repeated many times with no apparent degradation to the rubber.

A rubber band would have a low tensile set percentage. Elongation is proportional to applied strength. The door was hard to close because the. It is resilient and yet exhibits internal damping.

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. Which response is correct with additional information which is now in a question comment.
