Vibrating beam partially embedded in Winkler-type foundation

The fundamental frequency of transverse vibration of a beam with intermediate supports and partially embedded in a Winkler-type foundation is determined using the Rayleigh-Schmidt approach. The displacement function is approximated using polynomials that contain an exponential optimization parameter.
