Esmarch bandage (also known as Esmarch's bandage for surgical haemostasis or Esmarch's tourniquet) in its modern form is a narrow (5 to 10 cm (2.0 to 3.9 in) wide) soft rubber bandage that is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet. The limb is often elevated as the elastic ...
A kneaded eraser, also commonly known as a putty rubber, is a pliable erasing tool used by artists. It is usually made of a grey or white unvulcanized rubber (though it can be found in many different colors, such as green , blue , hot pink , yellow , and so forth) resembling putty or chewing gum.
Rubber elasticity is the ability of solid rubber to be stretched up to a factor of 10 from its original length, and return to close to its original length upon release. This process can be repeated many times with no apparent degradation to the rubber. [1] Rubber, like all materials, consists of molecules.
An eraser (also known as a rubber in some Commonwealth countries, including South Africa [1] [2] [3] from which the material first used got its name) is an article of stationery that is used for removing marks from paper or skin (e.g. parchment or vellum). Erasers have a rubbery consistency and come in a variety of shapes, sizes, and colors.
A rubber band ball is a sphere of rubber bands made by using a knotted single band as a starting point and then wrapping rubber bands around the center until the desired size is achieved. The ball is usually made from 100% rubber bands, but some instructions call for using a marble , [ 16 ] a crumpled piece of paper , or a ping-pong ball [ 17 ...
The free energy expression derived from the Neohookean model of rubber elasticity is in terms of free energy change due to deformation per unit volume of the sample. The strand concentration, v, is the number of strands over the volume which does not depend on the overall size and shape of the elastomer. [ 4 ]

Elastomers and shape memory metals such as Nitinol exhibit large elastic deformation ranges, as does rubber. However, elasticity is nonlinear in these materials. Normal metals, ceramics and most crystals show linear elasticity and a smaller elastic range. Linear elastic deformation is governed by Hooke's law, which states:
