2014年4月24日 · Hi, I'm doing an IB extended essay in physics (like a 4000 word investigation) and I'm looking to do it on Young's modulus- in particular perhaps how temperature effects it. Is this legit? Like does temperature have a significant effect, in such a way that if young's modulus decreased with...

2010年11月27日 · Material 1 young's modulus = y1 material 2 young's modulus = y2 Homework Equations F/a = y L change / L o The Attempt at a Solution Given they are of the same length and radius. Is the "new" youngs modulus simply their weighted average: y new = 0.5 * (y1 + y2)

2013年3月22日 · The stress is equal to the strain times Young's modulus: σ = E ε If we eliminate the stress σ and the strain ε from these equations, we get [tex]\Delta L=(\frac{L}{AE})F[/tex] If you plot a graph of ΔL versus F, you will get a straight line through the origin with a slope (gradient) of L/AE. So E will be equal to L/A divided by the slope.

2013年1月27日 · We know that the Young's modulus of an object is defined as the ratio between its stress and strain: Y = σ/ε , or: Y = F*L/A*ΔL We also know that Hooke's law, which can be applied to any linear elastic object, can find spring constant: F = k*x , rearranged: k = F/x But is...

2017年10月23日 · I have a question regarding finding the Young’s modulus of a rod by loading a weight to the end and measuring the change in displacement. The experiment is part of my advanced higher physics project on Young’s modulus however it is the only experiment that I’m doing that the book “Tyler” does not cover, and so I am slightly confused ...

2016年9月30日 · For Young's Modulus, stress is proportional to the applied force (as one factor) and strain is the amount of displacement in the material due to that amount of stress/force. In a physical application sense they are directly related in that the spring factor displacement is related to the amount of tensile or torsional strain (depending upon the ...

2021年2月3日 · The Young's modulus is defined for the unstrained material as is the length L. It is really applicable for small values of the strain x/L. The effects you are worried about refer to the effect of the stretch on the "effective" Young's modulus and so the manifestation in the energy will be ##(x/L)^ 2##.

2022年11月14日 · Equivalent Modulus Young modulus Young's modulus In summary: From there, the equivalent wire can be used to calculate the strain and tension in the system. Therefore, in summary, the conversation discusses finding a single wire to support the load, determining the equivalent stiffness of the system, and calculating the strain and tensions in ...

2012年3月9日 · I am trying to calculate youngs modulus of elasticity for results from a tensile test but can't seem to get a figure close to that of the common figure for the material Material 0.1% carbon steel Area = 20 x 10-6 Yield force = 6009N Length increase at yield force = 0.537mm = 0.000537m Original...

2008年7月11日 · Youngs modulus of a cantilever, help please! [1] BACKGROUND: I am doing an experiment determining the young's modulus of a cantilever through principles of SHM (i.e. hypothesis: higher youngs modulus = higher frequency of oscillation. See the attached Pictures for the diagram (strobe is...
