Talk:Vibration of plates

I think that in circular plates, the frequency should be ω = λn^2/sqrt(β)

Frequency of rectangular plate

I think that the frequency formula should read

$\omega _{mn}={\sqrt {\frac {D\pi ^{4}}{2\rho h}}}\left({\frac {m^{2}}{a^{2}}}+{\frac {n^{2}}{b^{2}}}\right)\,.$

not

$\omega _{mn}={\sqrt {{\frac {D\pi ^{4}}{2\rho h}}\left({\frac {m^{2}}{a^{2}}}+{\frac {n^{2}}{b^{2}}}\right)}}\,.$

Is this correct? David s graff (talk) 20:32, 2 December 2015 (UTC)

You are correct. You can easily fix these typos on your own. Please do if you find other instances. Bbanerje (talk) 21:55, 2 December 2015 (UTC)

Image of circular plate vibrations

I think that the two gif of the vibration of circular plates are not perfectly correct: the gif seems to come from the "vibrations of a circular membrane" article but should not be perfectly the same (difference between cos sin and Bessel functions). The derivative of the function at the limit should be null, which is not the case. 194.57.171.11 (talk) 16:07, 13 October 2016 (UTC)
