| Abstract: | Based on the principle of optical lever method for measuring Young's modulus of elasticith on metal,by means of spiral micrometer,a set of experimental apparatus for measuring micro-extension on metal has been designed.The result of the experiment shows that the apparatus is more convenient than by traditional method,and the measures are reduced,the relative error is droped in a certain extent. |
