拉伸法测杨氏模量实验方法的改进

Improvement of Experiment of Young' s Module by Stretching

改进拉伸法测量杨氏模量的实验方法,用游标卡尺测量金属丝承重时的伸长量,改变传统的实验方法,简化测量装置,提高测量精度.

This essay is to improve the experiment of young's module by stretching. This is to use vernier to measure the amount of wire' s elongation when bearing and change the craditional experiment, simplify the measuring device and improve the measuring accuracy.
