Vibration in Composite Beams: A Note on Natural Frequencies of Uncoupled Flexural and Torsional Vibrations of Composite Beams

AN aeroplane wing and fuselage may be treated from an analytic standpoint as two elastic beams, rigidly connected. In the present note the equations for the natural frequency, derived on the basis of Rayleigh's principle and Ritz's method, are extended to the case of free vibration of a set composed of two such beams with a number of concentrated loads elastically suspended.
