Problem

A granite rod of 60 cm length is clamped at its middle point and is set into longitudinal vibrations. The density of granite is

2.7 \times 10^3 \text{ kg/m}^3

and its Young's modulus is

9.27 \times 10^{10} \text{ Pa}

. What will be the fundamental frequency of the longitudinal vibrations? (1) 5 kHz (2) 2.5 kHz (3) 10 kHz (4) 7.5 kHz
