Resonant frequency method young's modulus

WebThe frequency spectrum is computed and displayed by the meter. Three different modes of vibration are measured: longitudinal, transverse (flexural), and torsional. Samples with cross-section up to 6in (150mm) and length from 1.75in (45mm) to 28in (700mm) can be tested. The frequency range is 10Hz to 40kHz, with 4.9 to 78.1Hz resolution. http://www.isjos.org/ISJOSv9p1-WineglassYoungs.pdf
