Eigenfrequency of simple supported beam with overhang?

WebbNatural Frequency of Simply Supported Beam. When given an excitation and left to vibrate on its own, the frequency at which a simply supported beam will oscillate is its natural frequency. This condition is called Free vibration. The value of natural frequency depends only on system parameters of mass and stiffness. WebbEvery beam, of any length, has one natural frequency for each wave (mode) it can generate and it can only generate an exact number (integer) of waves between its supports that is, it can generate 1 wave (2 nodes), 2 waves (3 nodes), 3 waves (4 nodes), etc. but it cannot generate a non-integer number of waves; 1.25, 2.47, 6.1, etc..
