Perfectly Elastic Bodies: Elasticity is that property of the object by virtue of which it regain its original configuration after the removal of the deforming force. It has no unit and it is a dimensionless quantity. Practical Applications of Elasticit.. Elasticity is that property of the object by virtue of which it regain its original configuration after the removal of the deforming force. The fractional change in configuration is called strain. Elasticity:-The property by virtue of which a body tends to recover its original configuration (shape and size) on the removal of the deforming forces, is elasticity. Potential energy U = Average force * Increase in length, = 1 / 2 Stress * Strain * Volume of the wire, Elastic potential energy of a stretched spring = 1 / 2 kx2. Download Elasticity (Physics) notes for IIT-JEE Main and Advanced Examination. Plasma occurs in the atmosphere of stars (including the sun) and in discharge tubes. modulus of rigidity is zero. The elastic modulus has the same physical unit as stress. where, k = Force constant of spring and x = Change in length. When temperature of a gas enclosed in a vessel is changed, then the thermal stress produced is equal to change in pressure (Δp)of the gas. Strain = Change in the configuration / Original configuration. (iii) Shearing strain = Angular displacement of the plane perpendicular to the fixed surface. Young’s modulus (Y) and modulus of rigidity (η) are possessed by solid materials only. Download 12th class elasticity chapter notes in physics document.

Hoogenboom CT5141 August 2003 21010310399. Notes for NEET Physics Elasticity. Thanks heaps! Price elasticity of demand, also called the elasticity of demand, refers to the degree of responsiveness in demand quantity with respect to price. Elasticity defines a property of an object that has the ability to regain its original shape after being stretched or compressed. The modulus of elasticity is simply the ratio between stress and strain. Elastic Potential Energy in a Stretched Wire. Its unit is N/m2 or Pascal and dimensional formula is [ML-12T-2]. Steel is more elastic than rubber. The property of matter by virtue of which it regains its original configuration after removing the deforming force is called elasticity. γ = coefficient of cubical expansion of the gas. Those bodies which regain its original configuration immediately and completely after the removal of deforming force are called perfectly elastic bodies. From a general summary to chapter summaries to explanations of famous quotes, the SparkNotes Elasticity Study Guide has everything you need to ace quizzes, tests, and essays. Elasticity is a measure of a variable’s sensitivity to a change in another variable, most commonly this sensitivity is the change in price relative to changes in other factors. For liquids. Summary ⇒ The following image shows an unfortunate situation: a van fails to stop as it approaches a line of traffic and hits a stationary car; and they move forwards together - is this elastic or inelastic collision? Learn about the deforming force applied on an elastic object and how the stress and strain works on an object. Substances that display a high degree of elasticity are termed "elastic." What is a Hooke’s law and how it is applicable for the concept of elasticity. The amount of deformation is ll d th t i Elastic deformation Elastic limit is the upper limit of deforming force upto which, if deforming force is removed, the body regains its original form completely and beyond which if deforming force is increased the body loses its property of elasticity and get permanently deformed. where, η = modulus of rigidity of the material of cylinder, Work done in twisting the cylinder through an angle θ, Relation between angle of twist (θ) and angle of shear (φ), rθ = lφ or φ = r / l = θ Its practical value lies between 0 and 0.5. 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. Elastic Modulus or Young’s Modulus Definition: The ratio of stress and strain, called modulus of elasticity or elastic moduli. You can see that if the price changes from $.75 to$1, the quantity decreases by a lot. Those bodies which does not regain its original configuration at all on the removal of deforming force are called perfectly plastic bodies, e.g., putty, paraffin, wax etc. If there is an increase in length, then stress is called tensile stress. putty, paraffin, wax etc. ∴ Poisson’s Ratio (σ) = Lateral strain / Longitudinal strain = – Δ R/ R / ΔU l.

Breaking stress is fixed for a material but breaking force varies with area of cross-section of the wire. Solid objects will deformwhen adequate loadsare applied to them; if the material is elastic, the object will return to its initial shape and size after removal. Learnengineering.in collected the various Topic wise notes for JEE(Joint Entrance Exam).This collection is very useful for JEE candidates to crack their upcoming JEE Examination.. Coefficient of elasticity depends upon the material, its temperature and purity but not on stress or strain. The property of an elastic body by virtue of which its behaviour becomes less elastic under the action of repeated alternating deforming force is called elastic fatigue. There are three types of modulus of elasticity, Young’s modulus, Shear modulus, and Bulk modulus. Perfectly Elastic Demand: A perfectly elastic demand refers to a situation when demand is infinite at the prevailing price. The elasticity of the strap determines the amplitude of the resulting vibrations. Solids are more elastic and gases are least elastic. 1. where, K = bulk modulus of elasticity and. 4, DD is the perfectly elastic demand curve which is parallel to OX-axis. Note : The fourth state of matter in which the medium is in the form of positive and negative ions, is known as plasma. It is defined as the ratio of tangential stress to the shearing strain, within the elastic limit. In this case, elasticity of demand is infinite or E 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. Candidates who are ambitious to qualify the Class 11 with good score can check this article for Notes. where, w = load, 1 = length of the cantilever.
