Determining young's modulus experiment

WebTheory: Young’s modulus means the ratio of longitudinal stress and longitudinal strain within elastic limit. It is denoted by Y. 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; Longitudinal stress = F/A = mg/A [here, g = acceleration due to ... WebJan 10, 2014 · In the paper, a new test method and test device based on a new three-point bending test are put forward to measure Young’s modulus of materials, and the main …

WebApr 1, 2024 · It would be interesting to see whether students would reach the same conclusion. Figure 4. The experimental results with the assumed steel guitar string. Although the results are in accord with the theoretical model, the determined Young's modulus (146 ± 2 GPa) does not accord with the theoretical value (210 GPa). WebIntroduction: Rubber bands stretch when we pull on them, but pulling as hard as you can on a 2-by-4 will probably have no visible effect. The stretchability of solid materials is expressed as their Young’s Modulus (a.k.a. “Elastic Constant”), Y. Here is the formula for Young’s modulus (Eqn.1): (1) Y = F A Δ L L 0.
