Physics 126 experiment no 1 young’s modulus in this experiment we test the linear relationship between stress and strain and determine the young’s modulus of copper the experiment is performed by placing a copper wire of known diameter under varying degrees of tension and measuring the resulting small. 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. Young’s modulus for copper of 36 per cent, on heating from 130 c to ioo° c miss noyes2 made observations at various temperatures up to 150° c and reports a uniform decrease of the modulus of 013 per cent. Young modulus if you plot a stress against strain of a material with the (linear) elastic behaviour, you get a straight line ie stress is proportional to strain the gradient of the above straight line is the young's modulus, e and e is constant and does not change for a given material, no matter what the size of the sample we test. 1 the problem statement, all variables and given/known data find the young modulus of copper through calculating the stress and strain, plotting on a graph and finding the gradient of the linear part of the graph 2 relevant equations ym=stress/strain stress=force/ area strain.

How to draw a young modulus graph hi, im doing the ym of copper wire for my physics as level coursework i done 5 experiments and calculated my ym for all of them, i know you meant to have a stress/strain graph so your young's modulus of the copper wire would be 32 +/- 15 (units. Young's modulus, also known as the elastic modulus, is a measure of the stiffness of a solid material it is a mechanical property of linear elastic solid materials it defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material. Young’s modulus e = initial slope of σt −εt curve = initial slope of σn −εn curve yield stress σ y is the nominal stress at the limit of elasticity in a tensile test tensile strength σ ts is the nominal stress at maximum load in a tensile test.

For my as physics coursework, i'm measuring the young's modulus of copper wire (30 and 32 swg) and brass (30 and 32 swg) i've already completed the experiment, have three sets of results for each of these wires, and can already see some trends between the wires. Young modulus a better measure 20 gauge copper wire, 22 young modulus of copper coursework copper wire, 30 pound fishing line and 20 gauge brass wire the problem statement, all variables and givenknown data find the young modulus of copper coursework modulus of copper through calculating the stress and strain, plotting on a. Poisson's ratio and young's modulus determine the deformations of materials carbon nanotubes are the earlier nanoscale structures and their poisson's ratio depends on both the imposed strain and the chirality [1] , [2]. Physics 801x fall term 2002 young’s modulus in this demo we measured the value of young’s modulus for a copper wire the setup is shown in the ﬁgure (not to scale) wire δx l d m 2 θ laser d θ young’s modulus is deﬁned as fperp/a y = (1) x/x.

Under elastic conditions, a modulus of elasticity of a wire, called the young modulus e, is defined as the ratio of the tensile stress applied to a body to the tensile strain produced where e is expressed in n m-2 or pascal (pa) we will write a custom essay sample on measuring young’s modulus of copper specifically for you for only $16. Young's modulus - wikipedia young's modulus, also known as the elastic modulus, is a measure of the stiffness of a solid for example , carbon fiber has much higher young's modulus (is much stiffer) when force is loaded parallel to the fibers (along the grain. Young's modulus is the ratio of the stress to the strain, that is: young's modulus = stress/strain for the material i predict that a graph of extension against load will be a straight line through the origin, provided the elastic limit has not been reached, the gradient will give us the young’s modulus.

Young's modulus is a mechanical property that measures the stiffness of a solid material it defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation young's modulus is named after the 19th-century british scientist thomas younghowever, the concept was developed in 1727 by. Young's modulus of elasticity is a measure of the stiffness of a spring member stiffness is an important factor in spring design because it, too, affects contact force this is readily seen from the equations that relate deflection to contact force. Determination of mechanical properties of pcb nilesh r bhavsar1, h p shinde2, mahesh bhat3 1student, coe, variation effect of in-plane modulus e x and e y is not (thickness of one copper layer) e c= copper young‟s modulus of elasticity e xl = laminate modulus in x-direction (calculated by.

- The young’s modulus of copper is 125×10^11n/m^2 a wire of this material has 1mm diameter how much kg-weight should be suspended to produce 01% incr.
- A-level applied science/choosing and using materials/properties from wikibooks, open books for an open world young modulus a better measure than stiffness is the young modulus (as opposed to brittle fracture, which yields under normal stress) gold, copper, and aluminium are highly ductile metals electrical conductivity see also:.
- Young's modulus 128 gpa vias,used in a cell composed of a square copper via in a thin polyimide film mounted on top of a silicon substrate,properties are taken same as bulk properties.

Young’s modulus has been determined for aluminium, copper, iron, brass and certain steel alloys by using dehi technique the samples for this purpose were obtained from mayura steel industries, kolhapur. Young's modulus is defined as the ratio of stress below the proportional limit to the corresponding strain it is a measure of the rigidity or stiffness of a material in terms of the stress-strain curve, young's modulus is the slope of the stress-strain curve in the range of linear proportionality of stress to strain. Tensile modulus - young's modulus or modulus of elasticity - is a measure of stiffness of an elastic material it is used to describe the elastic properties of objects like wires, rods or columns when they are stretched or compressed. The young’s modulus is a measure of elasticity and stiffness of a specific material strain is the proportional percentage of extension in comparison to the original length.
