Viva voce. Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. Procedure. Video. Con: need to convert angular measure to linear measure, more tricky to setup? Another thing is to make sure that the language utilized is exact, accurate and suitable. 2. It’s a summary of what you have actually done. Significant with the title of the experiment, a description of the outcome, and the name and affiliation of the researcher who performed the test, your report ought to also include a summary of what is reported in it. Close suggestions. What does this mean? Ask students to identify the quantities to be measured, how they might be measured, and so on. The Young's Double Slit Experiment Interactive is shown in the iFrame below. YOUNG’S MODULUS PRACTICAL OBJECTIVE • To determine the Young’s Modulus of a steel wire using a graphical method. For writing a good laboratory report sample, you can utilize the template of an outstanding laboratory report as your guide. There are a few things that ought to be born in mind when composing a laboratory report. What do I do now I’ve composed my laboratory report? Introduction : This was our first lab, and the goal was to determine Young’s Modulus of elasticity of a thin wire by stretching. Clicking/tapping the hot spot opens the Interactive in full-screen mode. Share. 16-19. This ScienceStruck post explains how to calculate Young’s modulus, and its relation to temperature changes and Hooke’s Law. The Young modulus of a material is an intrinsic, bulk property that describes how the material deforms when subjected to... Glossary Definition 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 . Related documents. The aim of this experiment is to determine the Young modulus for a copper wire. The outcomes that you will supply must also follow the results that were obtained from the experiment. Alternative metal wires can be used of course. When a metal wire is stretched beyond its elastic limit then its cross section is reduced i.e. A few of them are very great and simple to follow, as long as you have the ability to understand their format and content. Look at the definition: we need to measure load (easy), cross-sectional area A , original length x0 (so make it reasonably long), and extension Δ x . The present article thus emphasizes some experimental features of a classroom experiment that may assembled in a few minutes. The hardness and elasticity of the material are profoundly affected. What needs to be measured? Information about the use of precision instruments (micrometer screw gauge, Vernier callipers and Vernier microscope). 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. Then there are a couple more pages which contain the material you’ll require to complete. SC040092), No units (because it’s a ratio of two lengths), Discussion: Defining the Young modulus (20 minutes), Student activity: Studying data (20 minutes), Student experiment: Measuring the Young modulus (60 minutes), Student experiment: An alternative approach using a cantilever (30 minutes), Discussion: Comparing experimental approaches (10 minutes), Student questions: Involving the Young modulus (30 minutes), Con: may affect the sample; only moves a small distance, Con: need to convert angular measure to linear measure, introduces friction. 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. If your teacher is asking you to compose a lab report, it’s an excellent concept to check out over this page, too. These changes increase with repeated drawings. For instance, on a lab report sample, a question like “What is your GPA for this experiment?”. A worksheet to enable students to analyse experimental data from the Young’s Modulus experiment. Risk Assessment 6. 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). It is a … and point out how the problems have been minimized. Animation. good and superb. Ask students to identify the quantities to be measured, how they might be measured, and so on. AppliedStatics (eme1016) Uploaded by. Course. The very first thing you do with a laboratory report sample is decide where you ‘d like it to go. Young’s Modulus and Poisson’s Ratio Solid Mechanics Lab #2 Hyungjun Kang 00939822 9/9/2014 Purpose: 1. Searle’s apparatus is used for the measurement of Young’s modulus. Laboratory reports are used to explain the research study results. Select environment: Select wire material: Wire radius: 0.1 mm 0.1 0.5 Wire length: 0.5 m 0.5 1. 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). Audiobooks. 3. Home. Cite this Simulator: Developed by Amrita Vishwa Vidyapeetham & CDAC Mumbai. The Young modulus is often regarded as the quintessential material property, and students can learn to measure it. (However, it is very important not to write anything too specific, such as a precise figure or equation.) Questions involving stress, strain and the Young modulus, including data-handling. Young’s modulus is named after Thomas Young,19th century,British scientist. 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. 2 Apparatus required They should be legible and must be provided in a clear and concise manner. Questions 1. Podcasts. 14-16. Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc.
