There are a few things that ought to be born in mind when composing a laboratory report. Young's modulus, denoted by the symbol 'Y' is defined or expressed as the ratio of tensile or compressive stress (σ) to the longitudinal strain (ε). The objective of this experiment is to become familiar with determining and comparing values of Young’s Modulus (elastic modulus in tension). In this experiment I am going to determine the young’s modulus (E) of wood from the period of oscillation of a loaded wooden ruler. Young’s modulus–the most common type of elastic modulus, seems to be the most important material property for mechanical engineers. Simulator. Then the graph can be analysed to determine E. Each frame is suspended from two identical wires, one being an ’experimental wire’ and the other being an ‘auxiliary wire’. Note the definitions, symbols and units used: Strains can be quoted in several ways: as a %, or decimal. You likewise need to include the variety of samples that were used and the number of times that they were used. Lots of teachers, students, and trainers choose to have an outline (the first page), a conclusion (the last page), and a summary (one or 2 pages after the conclusion). Viva voce. All real materials are Elastic and deform to some extent. 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. and is calculated using the formula below: So a fiducial marker such as some tape can be used to help identify the original and extended lengths. 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. in the class. 2 Apparatus required For instance, if your teacher desires to know your grade point average (GPA) in this lab experiment (e.g., “Did you get it down right?

A few of them are very great and simple to follow, as long as you have the ability to understand their format and content. If the area of cross section of the wire is 1. Feedback. Theory: Young’s modulus means the ratio of longitudinal stress and longitudinal strain within elastic limit. There are many examples online that might be extremely valuable. E.g. It’s a summary of what you have actually done. 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. 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. Give different groups different materials, cut to different sizes, for example: metal wires (copper, manganin, constantan etc), nylon (fishing line), human hair (attach in a loop using Sellotape), rubber. “), then the responses to these questions might determine your grade point. Good experimental practice: measure extension when adding to the load and when unloading, to check for any plastic behaviour. Your report should include the findings and observations of your experiments, the outcomes acquired from the experiments, and any additional information that will work for readers. It is a … Share. 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). Y = σ ε. Demonstration: By stretching confectionery laces, students learn that extension is not always proportional to load. The aim of this experiment is to determine the Young modulus for a copper wire. 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. Our use of materials characterises our history (Stone Age, Iron Age, etc.) Resources. 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. Bestsellers. Young’s modulus, used as a numerical constant. 2. Chai Hao. 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.
