Abstract：Young's modulus is an important mechanical parameter to describe the elastic deformation resistance of solid materials, and its accurate measurement is of great significance in scientific research and technical application. Through in-depth research and practice, this study improves and innovates on measuring instruments, replaces the optical lever method commonly used in college physics experimental courses by drainage method to realizes indirect measurement of metal wire drawing length variation. The experimental equipment of this device is simple in structure, convenient operation, cheap, not easy to be damaged, easy to disassembly and assembly, accurate and stable reading, and has high promotion value. It is suitable for students to carry out experimental research on the measurement of Young's modulus of metal wire.
