Linli MA, Xiaojie Wang · Wuli yu gongcheng. · 2023
Young's modulus measurement is one of the most important basic experiments in university physics experiments. This paper designs an experimental device and method based on Arduino to measure the Young's modulus of metal by using the optical lever amplification method, and introduces a photosensitive resistor to measure the small deformation of the brass rod under different stress conditions. The results show that the experimental measurement accuracy is relatively high. Through this experimental design, it can effectively stimulate students' interest in experiments, exercise students' hands-on ability, and cultivate students' innovative ability.
