This page allows you to compute the frequency resonances for the first four modes of a thin beam in bending vibrations (Love-Kirchhoff theory) with various boundary conditions. Change dimensions, materials parameters, boundary conditions or mode to compute a new natural frequency.
Refer to the Beam beending page to read how these natural frequencies are computed.
