Young's modulus depends only on the material, not its geometry, thus allowing a revolution in engineering strategies physics (coursework and research report) - wits university mexico tech rankings by college factual include ranking our nmt physics department as #1 in the nation for best. Young's modulus graphs by horsforthphysics 1294 views hooke's law by aulia rodlia 3975 views share slideshare use your answer to 1 to determine the young modulus of the material of the wireevaluationthe procedure you carried out including what steps were taken to reduce error1. Young's modulus is a material property that tells you how stiff or stretchy a material is in this lesson, learn how to calculate young's modulus and what it can tell you about the material. It features in some a level equivalent courses pulleys - a level physics a review of pulleys, mechanical advantage, an inclined surface as physics exam question: materials examples of exam questions at physics as level for materials (hookes law, youngs modulus, viscosity) covering. Work, energy and power electricity particle physics electromagnetic radiation and quantum phenomena waves and vibrations materials and young's modulus.

Young's modulus or modulus of elasticity young's modulus definition: it is defined as the ratio of tensile stress or compressive stress to the corresponding strain within elastic limit e = tensile or compressive strain the si unit of youngs modulus is n/mm2. Deriving young's modulus from atomic forces the curves shown above are simple polynomials young's modulus y for a material is defined as the ratio of tensile stress to tensile strain the tensile stress is the force per unit area f/a, and the strain is the proportional increase in length parallel to the. Within the proportional limit and accuracy of the lab data (and applicabilty of hooke's law for the spring), you should get a straight line relationship of force versus displacement, where the slope of the graphed line is the spring constant, k.

Young's modulus is the ratio of stress (force per unit area) over strain (deformation per unit length), so you need the applied force, the cross-sectional area, the initial length, and the deformed length. Young's mod exists today as giant fighting robots, avail for ipod, ipad, and iphone at the app-store it is fun. Table of contents young's modulus hanging a mass from a platinum wire young's modulus connecting the microscopic and the macroscopic examples section 45 and 46 in matter and interactions (4th edition) young's modulus. Young's modulus is used to represents how easy it is to deform a material a modulus is a numerical value, which represents a physical property of a material it compares the tensile stress with the tensile strain this is written as: young's modulus = (force no-stress length) / (area of a section. Young modulus instead of drawing a force - extension graph, if you plot stress against strain for an object showing (linear) elastic behaviour, you get a straight line this is because stress is proportional to strain the gradient of the straight-line graph is the young's modulus, e e is constant and does.

The modulus of elasticity for a variety of common materials - references for youngs modulus with worked examples in structures the young's modulus has importance in calculated the deflection or extension of beams due to applied loads, enabling an induced stress to be converted into a strain. Resources to help support the young's modulus practical element of a-level, suitable for all of the main exam boards the young's modulus (e) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε) where. Young's modulus is a measure of how difficult it is to compress a material, such as steel it measures pressure and is typically computed in terms of pascals (pa) it is most commonly used by physicists to determine strain, a measurement of how a material, responds to a pressure, such as being. Young' modulus is the quantity that tells us how much a material will deform, elastically, when subjected to a force/tension from my understanding, young's modulus (aka modulus of elasticity ) is dependent on the bond strength (energy) at the atomic level.

Online physics tutorialsphysics model provides online learning physics courses and tutorials which cover topics required for class 10 to 12 for cbse & icse board this course is meant to give a comfortable and smooth start to your maths basics, as needed for physics topics explained. Young's modulus is a measure of the stiffness of a solid material it is calculated only for small amounts of elongation or compression which are reversible and do not cause permanent deformation when the external applied force is removed for this reason, it is also called elastic modulus. In solid mechanics, young's modulus (also known as the modulus of elasticity or elastic modulus) is a measure of the stiffness of a given material it is defined as the limit for small strains of the rate of change of stress with strain.

Young's modulus young's modulus is a measure of the stiffness of a material, and describes how much strain a material will undergo (ie how much it will stretch) as a result of a given amount of stress. Young's modulus (y) = not calculated original length young's modulus stress strain references - books: tipler, paul a 1995 physics for scientists and engineers. Young modulus mcqs test online, young modulus multiple choice questions and answers pdf to learn a level physics online course young modulus quiz questions with answers on simple harmonic motion gravitation, rigid body rotation, dynamics for online high school physics class courses distance learning.

The young modulus this is defined as the ratio of longitudinal stress to longitudinal strain this is the modulus we need if we want to investigate the change of length of a object - more accurately any linear dimension (width, length or height. It is the modulus of elasticity this means it is a number which represents how easy it is to deform (stretch a material) when a material is stretched stress is directly proportional to strain provided it is not stretched beyond the limit of proportionality. A211 - young modulus is not available as physics - a participants resources for teacher a.

Where δl is the change in length, f the applied force, y is a factor, called the elastic modulus or young's modulus, that depends on the substance, a is the cross-sectional area, and l 0 is the original length. Hey, is anyone doing there physics coursework on young's modulus or no where i can find loads of information about youngs modulus for my planning section. Young's modulus (also referred to as the elastic modulus or tensile modulus), is a measure of mechanical properties of linear elastic solids like rods, wires and such there are other numbers which give us a measure of elastic properties of a material, like bulk modulus and shear modulus, but the value of young's modulus is most commonly used.
