| Abstract: | Based on the measurement of Elastic Modulus by using stretching methods,the experiment was modified by using the dial indicator properly.By introducing dial indicator in the experiment of the measurement of Elastic Modulus,the experimental setup is simplified,the lab space is saved,and the shortcomings,such as too much indirect measurements,too long experiment time are avoided effectively. |
