Instrument for Young's modulus determination from frequency vibration analysis (proximity sensor) of a cantilevered beam. A scale is also included (HX711 and Load Cell) to determine magnet's mass... Frequency and mass are displayd on LCD 16x2 i2c.
For a given length and thickness of a cantivelered beam (one end free), depending of the material under study, the bar vibrates at a given frequency. Then adding knon mass, we can estimat both Young's Modulus and density of the material.
