| Abstract: | The deformations and the internal forces at a cross section of a beam are taken as state variables to formulate a general equation for computing the natural frequencies of non uniform beams.This method is suitbale for various non uniform beams with different constraints at their ends such as stepped beams,continuous variable beams,and beams with elastic bears or concentrated masses. |

| Keywords: | beam natural frequencies state variable |
