Experiment: Determination Of Young’S Modulus

Di: Ava

This document outlines the required practical to determine the Young’s modulus using a simple method. The experiment involves measuring the extension of a steel wire when hung with increasing 1kg masses and calculating the Young’s modulus from the slope of a stress-strain graph. Safety goggles and a sand tray are required due to the risk of the tightly stretched wire

DETERMINATION OF THE YOUNG’S MODULUS OF THE MATERIAL OF A BAR BY THE METHOD OF FLEXTURE APPARATUS : A bar of uniform rectangular cross section and of length about 1 m made of material whose Young’s modulus is to be determined. Two stout iron stands with leveling screws at the base and sharp knife edge fixed at the top, a rectangular stirrup with

Repeat the experiment with wires of different materials, if available. Change the length of the experimental wire, of same material and study its effect on the Young’s modulus of elasticity of the material. Holmarc’s Young’s modulus apparatus (Model No: HO-ED-M-02) is used to measure the Young’s modulus of a bar. Young’s modulus is a measure of stiffness of an elastic material and is a quantity used to characterize materials. The Young’s modulus of elasticity was calculated using fringe count, load applied and dimension of the cantilever plate. The value comes to be 69.92GPa.The Young’s modulus is also determined using UTM and is used to compare with the value calculated by

Abstract The paper presents details about the adequate experimental determination of the Young’s modulus on miniaturised specimens for material used in electronic packaging. The difficulty to determine accurately the Young’s modulus is caused by the requirements of representative specimens for the area of electronic packaging.

II. THEORY AND EXPERIMENTAL METHOD (a) Metal The machine used in this experiment was an electronic extensometer (see Fig 1) with very high resolution and accuracy which allow the determination of Young‘s modulus and yield point. It permits quick and easy examination of a large number of test samples and guarantees a high level of reliability. The objectives of this practical are 1. to demonstrate Hooke’s law; 2. to determine the Young’s modulus, Poisson’s ratio and shear modulus of an unknown material; 3. to check the inter-relation of , and ; 4. to make reasoned estimates of experimental errors; 5. to think about how to minimise errors in performing measurements. 1 Introduction One-dimensional carbon nanotube (CNT) with certain chirality exhibits high aspect ratio, low density, high modulus, and high strength. The excellent mechanical properties of CNTs have attracted extensive and in-depth attention since their discovery [1, 2]. Previous studies showed that the Young’s modulus (YM) of single-walled carbon nanotubes (SWCNTs) is in the

This video explains the full procedure of the experiment to determine the young’s modulus of a material by bending of the beam.============================= Weights are added to the weight hanger in steps of 0.5 kg upto 4 kg and in each case the micrometer reading is noted by adjusting the spirit level. If ∫ is the original length and r the mean radius of the experimental wire, then Young’s modulus of the material of the wire is given by: q = (F/A) / (dl/∫) = (F/πr2) / (dl/∫) so, q = F∫

Youngs Modulus Experiment Questions and Answers for Viva Frequently asked questions and answers of Youngs Modulus Experiment in Physics Lab Instruments of Physics to enhance your skills, knowledge on the selected topic. Theory Young’s Modulus or modulus of elasticity is primarily a material property alone. It is independent of the type or class of structure wherein it is employed. It should be a straight line through the origin. The gradient of that graph will be e/F. Using that value we can find the value of Young’s Modulus for the wire.

A methodology for determining Young’s modulus of materials by non-ideally sharp indentation has been developed. According to the principle of the same area-to-depth ratio, a non-ideally pyramidal indenter like a Berkovich one can be approximated by a non-ideally conical indenter with a spherical cap at the tip. By applying dimensional and finite element analysis to the non
