WebAnswer: Ah, let Chen Homework Experts Nonpareil (CHEN) help you with this. First, the work dU done by load P on your wire will stretch it by some tiny amount dx. That is, dU = Pdx. … WebA measure of stiffness that is independent of the particular sample of a substance is the Young modulus E. Recall other examples you have already met of sample independent properties that only depend upon the substance itself: density = mass volume electrical resistivity = resistance × area length

The Young

Web20 Apr 2016 · Theory. Young's modulus is the measure of elasticity, equal to the ratio of stress acting on a substance to the strain produced. When weight is added to wire, it experiences stress and strain. However, it is hard to notice it. By using an optical lever, the change in length can be measured. The wire is wrapped once around a cylindrical chuck. WebThe Young's modulus of a wire of length (L) and radius (r) is Y N-m⁻2. If the length is reduced to L/2 and radius to r/2, then Young's modulus for the wire will bea)Y/2b)Yc)2 … WebThe young’s modulus of a wire of radius R and length L is Y N/m2. If the radius and length are changed to 2R and 4L respectively, then its young’s modulus will be ? A wire extends 1 … arun raghupathy
