Modeling and analysis of Sompoton vibrator using cantilever beam model

Sompoton is one of the famous traditional musical instruments in Sabah. This instrument consists of several parts with the vibrator being the most important of all. In this research, the vibrator is modeled as a cantilever beam with uniformly distributed mass. Using this model, the fundamental frequ...
