The upper bound of the fundamental bending frequency of a rotating uniform Timoshenko beam with general elastically restrained root is derived via Rayleigh's principle. Comparing the upper bound with the results in the existing literature and those obtained by the transfer matrix method reveals that

The ettects of rotational speed and root flexibilities on the static buckling loads and on the regions of dynamic instability of a Timoshenko beam are investigated by finite element method. Due to the action of rotation, the buckling loads are increased and the beam becomes less sensitive to periodi
A survey of the literature shows that the titleproblem has not been studied to any great extent. In the present paper an approximate solution is obtained in the case of a beam with ends elastically restrained against rotation and an intermediate support. A sinusoidally varying excitation is assumed.
