Angular Natural Frequency Beam Fixed-Free End Load Applied Equations and Calculator

ωn = [ ( 3 E I ) / ( m l3 ) ](1/2)

Where:

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

Note: 1 ( lbf-sec2 / Ft ) = 1 Slug

1 ( lbf-sec2 / in ) = 12 ( lbf-sec2 / Ft ) or 1 ( lbf-sec2 / Ft ) = 0.08333 ( lbf-sec2 / in )
