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

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

ωn = [ ( 48 E I ) / ( l3 ( m + 0.5 mb ) ] (1/2)

Where:

m = Mass of Load ( lb-sec2 / in ),
mb = 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 ),
ωn = Angular Natural Frequency ( rad / sec )
