Question:
A granite rod of $60 \mathrm{~cm}$ length is clamped at its middle point and is set into longitudinal vibrations. The density of granite is $2.7 \times 10^{3} \mathrm{~kg} / \mathrm{m}^{3}$ and its Young's modulus is $9.27 \times 10^{10} \mathrm{~Pa}$. What will be the fundamental frequency of the longitudinal vibrations?
