In this experiment, the young's modulus of copper will be mesured apparatus - copper wire 4m - g-clamp - polley on clamp -2wooden block - 2rule (half meter and meter rule) - slotted mass with hanger 15 0 1 kg - adhesive label -micrometer screw gauge -safety goggles -polystyrene board (warning : wear safety. Aim: to find the young’s modulus of a copper wire apparatus: -metre ruler -copper wire -micrometer screw gauge -10g and 20g weights -weight holder -microscope with vernier scales diagram: method: 1 the diameter of the piece of wire was measured with a micrometer screw gauge these measurements . Elastic properties and young's modulus for metals and alloys like cast iron, carbon steel and more sponsored links it is convenient to express the elasticity of a material with the ratio stress to strain , a parameter also termed as the tensile elastic modulus or young's modulus of the material - usually with the symbol - e .
Young’s modulus and poisson’s ratio are a measure of the stiffness of a material define stiffness stiffness is simply the ability of a material to resist deformation. Tensile strength of metals metal tensile strength n/m2 aluminum wire 24 x 108 copper wire, hard drawn 48 x 108 iron wire, annealed 38 x 108 iron wire, hard drawn 69 x 108. In the last lab, we were asked to find out the young modulus of two wires: copper and steel i worked on copper wire i worked on copper wire my hypothesis on the report was that “the young modulus of a wire is directly proportional to the extension possible by the object”. Young modulus of copper keyword after analyzing the system lists the list of keywords related and the list of websites with young's modulus copper wire .
Metallic bonding the young’s modulus measures how stiff a material is, i will be calculating the young’s modulus of copper wire i will . Modulus of elasticity is an important design factor for metals for calculations of elastic deflections room temperature modulus of elasticity values for some of the aluminum alloys, copper alloys, cast irons, various non-ferrous metals, steel alloys and titanium alloys are given in the following chart. What does the greater young's modulus of a steel than that of a copper mean what is the standard value of young's modulus for a steel and iron wire youngs modulus.
Example: for one of the extensions i used a weight of 01n, so i used that data to find youngs modulus, but when i did it for 02n it wasn't the same this has left me so confused. Young's modulus or tensile modulus alt modulus of elasticity - and ultimate tensile and yield strength for steel, glass, wood and other common materials tensile modulus - or young's modulus alt modulus of elasticity - is a measure of stiffness of an elastic material it is used to describe the . Please complete the enquiry form below for specific information and advice on modulus of elasticity – young modulus for some common materials fields marked with a ‘’ are mandatory and must be filled. A steel wire 10 m long and with a cross-sectional area of 001 cm 2 is hung from a support and a mass of 5 kg is hung from its end calculate the new length of the wire the young modulus for steel = 210 gpa. What is the precaution in measuring the young's modulus of copper a precaution would be to use an identical wire alongside and measure the extension of the test wire relative to it.
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). Youngs modulus(e ) density inconel x750 b637 11500000 31000000 0298 1100 berylium copper b197 7000000 18500000 0298 400 wire diamter music wire hard . Measurement of the young modulus the young modulus for a wire can be measured using this equipment the reference wire and test wire are hung from the ceiling the . The extension in the 0 28mm wire is the most consistent, and i feel that it will give me the readings needed to work out the young modulus of the copper wire however, we would not be able to see when the elastic limit is reached because of the limit in the load applied to the wire (1 10kg), unless we find a method of adding more weights.
I agree the value of e for typically annealed copper (like cf gaskets or home wire) are basically the same at 15e6 temperature effects of elastic modulus for . Material: copper (cu), bulk young's modulus: vias,used in a cell composed of a square copper via in a thin polyimide film mounted on top of a silicon . We will write a custom essay sample on the young’s modulus of the copper wire specifically for you for only $1638 $139/page.
According to the experiment findings the young’s modulus for a copper wire was found out to be 183gpa while that of wire thread was 5gpa materials with strong free essays. 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. Answer to a copper wire (with a young's modulus of 120 x 10^9 pa) of length 308 m is observed to stretch by 227 mm when a weight. E=4e10pa for the 019mm wire e=3e10pa for the 025 mm wire e=2e10pa the accepted value for the young’s modulus of copper is 110-128x 10^9pa, so our values are a long way out note the variation of more than 10% in the accepted value of the young’s modulus.
1 | page young’s modulus of copper abstract: i did an experiment to find the young’s modulus of a copper wire, which was resulted to be. To take measurements of a long wire to determine the young modulus for copper safety the wire will be under tension so safety spectacles should be worn.
