Academic year. Searle’s apparatus is used for the measurement of Young’s modulus. Young’s Modulus. The reference wire supports a vernier scale, which will measure the extension of the test wire. © 2021 IOP All rights reserved. There is a second hot-spot in the lower-right corner of the iFrame. Each frame is suspended from two identical wires, one being an ’experimental wire’ and the other being an ‘auxiliary wire’. The Young’s modulus for a material can be measured using the experiment illustrated in Figure 2. Young's modulus is a measure of how difficult it is to compress a material, such as steel. a 5% strain is 0.05. It is helpful if students can learn to find their way around tables of material properties. The Theory Before we move ahead, do you know what a Searle’s apparatus is?

A device dubbed the "Young's Modulus Apparatus" was assembled for the purposes of this experiement and used for the testing of each material. The Young Modulus is named after Thomas Young (1773 to 1829) who was a British polymath, contributing to our understanding of optics, physiology, and Egyptology, among other fields. 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. Laboratory reports are used to explain the research study results. Figure 3. Young’s modulus Experiment Young’s modulus Experiment. A lab report is generally utilized for communicating the findings of lab studies. (Scholz et al., 2008). 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. Young’s modulus, numerical constant, named for the 18th-century English physician and physicist Thomas Young, that describes the elastic properties of a solid undergoing tension or compression in only one direction, as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length. Lab Report Sample is often followed by a last paragraph. Young’s Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc. Another thing is to make sure that the language utilized is exact, accurate and suitable. 2 g is stretched between two fixed supports 4 0. So a fiducial marker such as some tape can be used to help identify the original and extended lengths. (It will probably snap!). Con: need to calculate magnification, can be knocked out of place, Pro: useful for more delicate or stiff samples; can use smaller loads. Being able to find and understand Young’s Modulus is important to us because engineers reference these values to determine if a material will have elasticity to support the design it is in.
