Young’s modulus determination for a vibrated metal ruler using Arduino

Abstract

Abstract The article introduces a low-cost Arduino sensor into the Young’s modulus determination laboratory for physics university students. A stainless steel ruler is used as a cantilever beam. Its free end attached a mass is slightly bent and released to make it oscillate as a simple harmonic motion. The Arduino sensor detects the moving mass’s frequency at different loaded forces. This technique shows an acceptable value of Young’s modulus for the used ruler.
