Each frame is suspended from two identical wires, one being an ’experimental wire’ and the other being an ‘auxiliary wire’. Problems? We used the concept of Hooke’s Law, which states that in a certain range, the strain or deformation of a material is proportional to the stress applied to it. Rather than using a note card to split the single beam into two coherent beams, a carbon-coated glass slide with two closely spaced etched slits is used. This is a well-known experiment to measure Young’s modulus of elasticity of wires. 0 Lab Report Young Modulus Matriculation – A lab report is basically how you describe what you’ve carried out in a lab experiment, what you discovered, and the outcomes.

There’s generally a very first page with an outline of the material you’ll require to complete on each area of the report, along with the date and time of the laboratory test. When a metal wire is stretched beyond its elastic limit then its cross section is reduced i.e. If at the lower end of wire of length ‘L’ and cross-sectional area of ‘A’ a load of ‘m’ is pressed and if the length increases by l, then; (Scholz et al., 2008). Extension – won’t it be quite small? Our website is made possible by displaying online advertisements to our visitors. © 2021 IOP All rights reserved. 2015/2016. INTRODUCTION: Young’s modulus is also known as tensile modulus. Is the sample uniform? It is a measure of the stiffness of a material that is independent of the particular sample of a substance. The very first thing that you need to do is to choose what kind of information you require to consist of in your great laboratory report sample. Course. 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). Young's modulus is a measure of how difficult it is to compress a material, such as steel. In the experiment in the video above, we measured the Young’s modulus of some copper wire which does not extend very much. The initial longitudinal Young modulus E 1 0 is determined directly using a tensile test on the fabric as shown in Fig. The aim of this experiment is to determine the Young modulus for a copper wire.

So a fiducial marker such as some tape can be used to help identify the original and extended lengths. Some of these are Bulk modulus and Shear modulus etc. The value of the Young's Modulus is quoted in scientific data manuals for various materials but the value given is only approximate. The device is simple in that it allows a test wire to be anchored in two places within a metal chasis that sits approximately 1.5 meters off the ground. Would you like to write for us? Video. It was named for the 18th-century English physician and physicist Thomas Young. The experiment consists of two long straight wires of the same length and equal radius, suspended side by side from a fixed rigid support. The Young's modulus is the property less dependent of the characteristics of the coatings (microstructure and morphology), but is strongly dependent of the chemical composition. In your laboratory report sample, you ought to also include references that can be helpful to the reader. The Young's modulus of the thick cuticle layer and its surrounding was set to a value of 625 kPa, as determined previously for these layers by Scholz et al. Different groups could try the different ideas they come up with. In 1782, Italian scientist Giordano Riccati performed experiments leading to modern calculations of the modulus. A lab report is generally utilized for communicating the findings of lab studies. The Young Modulus can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material. Measure the gradient of the straight portion of the graph and use this to calculate the Young modulus for the copper. For the horizontal set up: bridges over the sample to trap the flying ends, should the sample snap. It relates stress (force per unit area) to strain (proportional deformation) along an axis or line.The basic principle is that a material undergoes elastic deformation when it is compressed or extended, returning to its original shape when the load is removed. Method 5. 293851) and Scotland (no. You can make measuring the Young modulus E a more interesting lab exercise than one which simply follows a recipe. its structure is changed internally.
