Are two wires of the same material but different in thickness and length? Are their young's modulus of elasticity the same?
Not necessarily. Young's modulus is related to microstructure so on
The elastic modulus is the inherent property of the material and, once the material is determined, the modulus of elasticity has been determined, irrespective of shape
According to Hooke's law, in the elastic limit of an object, the stress is proportional to the strain, and the coefficient of proportionality is called the young's modulus (Y). Express as a formula:Y= (F - L) / (S - L)Y is numerically equal to the stress produced by unit strain. Its units are the same as those of the force. Young's modulus is the property of a material, independent of force and shape of an object.Young's modulus (Young's, modulus) is a noun in mechanics of materials. When the elastic material is subjected to the positive stress, it will produce a positive strain, defined as the ratio of the forward stress to the positive strain. The formula is denoted as E = sigma / epsilonAmong them, E represents Young's modulus, sigma represents positive stress, and epsilon represents positive strain.Young's modulus is large, indicating that in compression or tensile material, the deformation of the material is small.
identicalThe young's modulus depends only on the physical properties of the material itself, irrespective of the thickness or length of the material.Young's modulus characterizing the physical resistance of solid materials to deformation, and the physical quantities characterizing the properties of the material. The young's modulus reflects the rigidity of the material, and the greater the young's modulus, the less deformation it is prone to.I hope I can help you.
