Let the geometrical deformation of the structure under vibration, u(z, t), be separable into a product of independent spatial and temporal functions, U(z) and f(t), respectively. 55) where M(z) is the distributed mass. 10. 57) z0 x L z Figure 2-10 Quarter cosine wave as a Rayleigh shape for a cantilever. 59) where µ1 is the mass density per unit length. Rayleigh’s method is an approximate way of estimating the frequency of the first mode of vibration of a system, based on an assumed motion. However, if the assumed motion happens to be exact, then Rayleigh’s method gives the exact solution to the natural frequency.
