Beam Spring Fixed Ends with Concentrated Mass Loads Angular Natural Frequency Equations and Calculator

ω_n = 14 [ ( E I ) / ( l³ ( m + 0.375 m_b ) ] ^(1/2)

Where:

m = Mass of Load ( lb-sec² / in ),
m_b = Mass of Beam Spring ( lb-sec² / in ),
l = Length of Beam Spring (in),
I = Area Moment of Inertia of Beam Cross Section (in⁴)
E = Young's Modulus ( lb / in² ),
ω_n = Angular Natural Frequency ( rad / sec )
