Massless Circular Plate With Concentrated Center Mass Clamped Edges Natural Frequency Equations and Calculator

ω_n = 4.09 [ ( E h³ ) / ( m a² ( 1 - v² ) ) ] ^(1/2)

Where:

Nodes are indiated in images as a proportion of length l measured from the the left,
E = Young's Modulus of Plate( lb / in² ),
v = Poisson's Ratio
m = Mass of Load ( lb-sec² / in ),
a = Diameter of Plate (in),
h = Thickness of plate (in)

ω_n = Angular Natural Frequency ( rad / sec )
