【 摘 要 】

Young's modulus of solid material is usually measured by tensile test. We adopt a new laser lever to instead of the traditional optical lever in this article. Contrast experiments with two different methods are designed to measure the steel-wire's Young's modulus. The results show that the new method is more accurate and efficient than the old one.
