In a particular reading, the student measures the extension in the length of the wire to be 0.8 mm with an uncertainty of $\pm 0.05$ mm at a load of exactly 1.0 kg. Aim: The aim of this experiment is to measure the Young modules of copper wire. ANALYSIS AND CONCLUSIONS:
Plot a graph of F against e and hence find the Young Modulus for copper (E). Elasticity is a property of an object or material which will restore it to its original shape after distortion. Specimens with larger l o and ρ present more obvious measurement errors for Young's modulus, but the effect of ΔT is not significant. It should however be noted that the Young's modulus of a polycrystalline sample measured by the nanoindentation method is a little overestimated in comparison with the literature data [35,36] due to certain limitations of this method as the deformation is not strictly elastic. Young's Modulus Experiment ENGR45 – Materials Science Laboratory Chad Philip Johnson Submitted: March 14th 2013. Young modulus Young's modulus and temperature investigation as physics materials question Related articles. Working formula: l m bd gL Y. of experiments, namely, nanoindentation and Raman spec-troscopy, are being widely adopted to study the mechanical properties of graphene.

In the experiment in the video above, we measured the Young’s modulus of some copper wire which does not extend very much. For e.g. Working formula: l m bd gL Y. Light fr… Formula: The youngs modulus of material 1. Method 5. In solid mechanics, Young’s modulus is defines as the ratio of the longitudinal stress over longitudinal strain, in the range of elasticity the Hook’s law holds (stress is directly proportional to strain). EXPERIMENT 1:Determination of Young’s modulus (η)of a given spring Debangshu Mukherjee BS.c Physics,1st year Chennai Mathematical Institute 12.09.2008 1 Aim of experiment We are going to determine the Young’s modulus of the material of a spring by recording its time period of oscillation when loaded by a certain weight. It is a measure of the stiffness of a material that is independent of the particular sample of a substance. Unit of stress is Pascal and strain is a dimensionless quantity. Animation. Youngs Modulus Pin and microscope - Non Uniform bendingOn screen Soumya (Assistant Professor Physics Dept 2020) Conducting this experiment required bending thesteel beam using couples (up to 16N). Results were recorded in the results table. E = FL/eA
where A is the cross sectional area of the wire. A-level help … 11, 2016. A new experimental method for evaluating Young’s modulus of rust layer has been proposed by simply-supported 4-point bending tests. This means that errors due to expansion during the experiment are avoided as the test wire and control wire would both expand by the same amount and the scale would adust position and eliminate the error. Research a value for the Young modulus of copper and comment on your result. Accessed 11, 2016. https://www.essaysforstudent.com/Science/Measurement-of-Young-Modulus/104262.html.

Young’s double-slit experiment helped in understanding the wave theory of light which is explained with the help of a … Theory. It’s pretty important for materials scientists, too, so in this article I’m going to explain what elasticity means, how to calculate Young’s modulus, and why stiffness is so important. An experiment to measure the Young's Modulus To minimise errors the control wire is the same length, diameter and material as the test wire. Load the wire carefully and for each weight (F) record the extension (e) of the wire using the vernier scale. 11 2016. Table (set up for data collection) The force of the weight(F) needed to be calculated by the formulae F=mg. External forces acting on the body can cause (apart from the body movement in accordance with the principles of dynamics) also its deformation. "Measurement of Young Modulus." Hence, the unit of Young’s modulus is also Pascal. 15 Young’s Modulus Aim: To calculate the Young’s modulus of elasticity of the material of a bar by the method of flexure. Measure the gradient of the straight portion of the graph and use this to calculate the Young modulus for the copper. Aim To determine Young’s modulus of elasticity of the material of a given wire. Young’s modulus is named after Thomas Young,19th century,British scientist. Young's modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. It is a measure of the stiffness of a material that is independent of the particular sample of a substance. Experiment No. 2.
