  For this beam clamped at one end and free at the other, the first four undamped natural frequencies of vibration are 3.6Hz, 22.5Hz, 63.0Hz, and 123.5Hz. When the beam is struck, each mode of vibration, represented by the different frequencies, is excited to a different extent.

  The shaft is considered as simply supported beam undergoing transverse vibration or can be idealized as a pinned-pinned beam. Natural frequency can be found using the following equation, f nb f nb = π π 2 * EI m l 4 . Here, The moment of inertia of hollow shaft is given by,

  The mass of the structure is 5000 kg and is concentrated on the beam that is assumed to be rigid. The two columns are assumed to be mass-less and each has a flexural stiffness (EI) of 4.5x106 Nm2. If the structure has a damping ratio (ζ) of 4% (=0.04), calculate; (a) the undamped natural frequency and (b) the damped natural frequency.

  The Rayleigh method gives a natural frequency that is an upper limited of the true natural frequency. The method would give the exact natural frequency if the true displacement function were used. The true displacement function is called an eigenfunction. Consider the rectangular plate in Figure 1. The largest dimension may be either a or b ...

  One example of this is that the natural frequency that was determined analytically was found to be 29.58Hz, compared to 30Hz for the simple beam determined experimentally. This frequency was further verified by an impact test. Again a frequency of 30Hz was found by …
