Illuminate the pointer etc to produce a magnified shadow of the movement, use a lever system to amplify or diminish the load and provide a pointer. 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). Risk Assessment 6. 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. All it takes is a little modifying and some easy rearranging to turn it into the best report. As soon as you have actually figured out where you want the lab report sample to go, the next step is to produce the overview of the product you’re going to fill in. Part 1: To investigate the relationship between... View more. Bestsellers. 3. Young's modulus is given by the gradient of the line in a stress-strain plot. Set up (diagram or description) 4. Theory. Our aim is to determine the Young’s modulus of elasticity of the material of a given wire using Searle’s apparatus. The reference wire and test wire made of the selected material are hung from the ceiling. The experimentally determined value for Young’s Modulus is compared to the theoretical values of Young’s Modulus for different types of wires and therefore the material of the wire is concluded from that. Episode 228-6: Measure for measure (Word, 82 KB), An alternative approach to measuring the Young modulus is to bend a cantilever. The Theory Before we move ahead, do you know what a Searle’s apparatus is? “), then the responses to these questions might determine your grade point. a 5% strain is 0.05. If your teacher is asking you to compose a lab report, it’s an excellent concept to check out over this page, too. Although Young's modulus is named after the 19th-century British scientist Thomas Young, the concept was developed in 1727 by Leonhard Euler. 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. All real materials are Elastic and deform to some extent. A lab report sample is basically a beginning, middle, and end. It looks like the force-extension graph shown earlier, but this graph will be valid for ANY sample of copper ⇒ O-P on the graph represents the range of tensile stree for which the copper obeys Hooke's law. Our website is made possible by displaying online advertisements to our visitors. 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. It quantifies the relationship between tensile stress (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material and is determined using the formula: The experiment consists of two long straight wires of the same length and equal radius, suspended side by side from a fixed rigid support. 2 g is stretched between two fixed supports 4 0. Ask students to identify the quantities to be measured, how they might be measured, and so on. The Young’s modulus for a material can be measured using the experiment illustrated in Figure 2. its structure is changed internally. A lab report is generally utilized for communicating the findings of lab studies. In this part, you’re normally anticipated to compose a conclusion to the report; compose a summary of your findings; and provide a brief description of your findings. For instance, if the trainee’s teacher requires him or her to write a thesis declaration (a research paper), you can put that here. The reference wire supports a vernier scale, which will measure the extension of the test wire. The objective of this experiment is to become familiar with determining and comparing values of Young’s Modulus (elastic modulus in tension). When a metal wire is stretched beyond its elastic limit then its cross section is reduced i.e. Purpose This experiment is designed to determine Young’s modulus for a wire when it is stretched. wooden or plastic rulers, spaghetti, glass fibres) the deflection y of a cantilever is often quite easy to measure and is directly related to its Young modulus E .

Young's Modulus Experiment Lab report for Youngs Modulus Experiment. Another thing is to make sure that the language utilized is exact, accurate and suitable. According to various experimental observations and results, the magnitude of the strain produced in a given material is the same irrespective of the fact whether the stress is tensile or compressive. These changes increase with repeated drawings. Close suggestions. Today's classroom version of the same experiment is typically performed using a laser beam as the source. Procedure. What needs to be measured? Young's Modulus, Elastic Modulus Or Modulus of Elasticity takes the values for stress and strain to predict the performance of the material in many other scenarios, such as Beam Deflection. The formula of young’s modulus is stress by strain. It is most commonly used by physicists to determine strain, a measurement of how a material, responds to a pressure, such as being squeezed or stretched. Weight hanger weight: 0 kg 0 4. Depending upon the time available, it may be worth having some of the ideas already set up. The first experiments that used the concept of Young's modulus in its current form were performed by the Italian scientist Giordano Riccati in 1782, pre-dating Young's work by 25 years. Theory.
