Elasticity If an external force is applied to a material, it causes deformation in molecular structure of that material. Cork is an example of a material with a low Poisson's ratio (nearly zero). 0000015455 00000 n 0000015354 00000 n Most likely we'd replace the word "extension" with the symbol (This is Hooke's law for a spring — a simple object that's essentially one-dimensional.

Hooke's law can be generalized to…The coefficient that relates a particular type of stress to the strain that results is called an The international standard symbols for the moduli are derived from appropriate non-English words — Stresses on solids are always described as a force divided by an area. PM1: Elasticity 5 As the stress was further increased, a point Y, known as the yield point, at which the stress rapidly dropped, was reached. Trigonometry Formulas for class 11 (PDF download) Newtons law Interesting conceptual questions. Thicker nylon strings and ones made of steel stretch less for the same applied force, implying they have a larger k (see Figure 2). Pounding a rubber stopper into a glass flask with a mallet is likely to end in disaster.Surprisingly, negative Poisson's ratios are also possible.

If you don't see any interesting for you, use our search form on bottom ↓ . 4 Elasticity is the property of solid materials to return to their original shape and size after the forces deforming them have been removed. 0000014551 00000 n %PDF-1.4 %���� In Chaikin's Principles of Condensed Matter Physics, in chapter 6 ("Generalized Elasticity"), on pg. The proportionality constant k depends upon a number of factors for the material. Rubber on the other hand, has a high Poisson's ratio (nearly 0.5). It gets shorter and fatter. The quantity that describes how fluids flow in response to shear stresses is called The inability to shear also means fluids are opaque to transverse waves like the Fluids can resist a normal stress.

When a cork is pushed into a wine bottle, it gets shorter but not thicker. 0000006949 00000 n 0000015170 00000 n 3 Defining and Measuring Elasticity The price elasticity of demand is the ratio of the percent change in the quantity demanded to the percent change in the price as we move along the demand curve. Stretching a piece of dough makes it get thinner as well as longer. For example, a guitar string made of nylon stretches when it is tightened, and the elongation ΔL is proportional to the force applied (at least for small deformations).

By removing this force, material turns its original shapes; we call this process as elasticity of material. Gases have a bulk modulus that varies with initial pressure, which makes it more of a subject for thermodynamics — in particular the The SI unit of compressibility is the inverse pascal [Pa 0000011611 00000 n 0000011654 00000 n Download chapter 5 elasticity physics target notes pdf document. 0000013229 00000 n 0000016153 00000 n 0000006925 00000 n
