R.D. Mindlin has pointed out taht Timoshenko's shear coefficient, in Timoshenko's equations of flexural vibrations of beams, depends on both the shape of the cross-section and the mode of vibration. In this paper, it is demonstrated that Timoshenko's shear coefficient depends on three factors which are the shape of the cross-section, the mode of vibration and the Poisson's ratio of materials. In the cases of rectangular and circular cross-sections, the slower phase velocity obtained by shear coefficient constituted with three factors well coincides with that obtained by plane strain theory of elasticity and by Pochhammer-Chree theory respectively.
