Through this experiment, you can focus on the following: (1) experimental method: the young's modulus of the wire is measured by the elongation method. (2) measuring method: measuring small length change with light lever amplification method. (3) data processing method: the method of loop ...
A、杨氏弹性模量E仅决定于材料本身的性质,模量越大,物体越不容易变形。 Young's modulus of elasticity e only depends on the properties of the material itself. The larger the modulus is, the less likely the object is to deform. B、杨氏弹性模量E与外力ΔF,物体的长度L以及截面积S的大小有关,它是...

This paper proposes a new way,named Fraunhofer single slit diffraction method,to measure the Young.'s modulus for a wire.When the laser passes through the single slit,the diffraction fringe is formed by the means of measuring the change of diffraction fringe,and the wire's elongation can be ...

The utility model discloses an experiment scale for teaching the modulusof Young, including an outer tube and an inner tube. The experiment scale is characterized in that the inner tube is arranged in the outer tube to form a retractable tube. An enclosed end of the outer tube and an ...
IT was observed that, during annealing, the modulus of elasticity of copper wires may be appreciably lowered 1 . This phenomenon has been explained by Barrett 2 as resulting from alterations in their textures. As has been shown by Schmid and Wassermann 3 , most metals with a face-centred cub...
