\(\displaystyle I'll \ do \ the \ rate \ of \ change \ of \ frequency \ when \ the \ force \ (T) \ is \ varied.\)

\(\displaystyle Let \ n \ = \ f(T) \ = \ \frac{1}{DL} \sqrt \frac{gT}{\pi\sigma}\)

\(\displaystyle \frac{dn}{dT} \ = \ \frac{1}{DL} \sqrt \frac{g}{\pi\sigma} \ \frac{1}{2} \ (T)^{-1/2} \ = \ \frac{\sqrt g}{2DL\sqrt( \pi \sigma T)}\)
