WebThe formula for the natural frequency fn of a single-degree-of-freedom system is m k 2 1 fn S (A-28) The mass term m is simply the mass at the end of the beam. The natural … WebIn this case, the frequency of natural vibrations will be equal to: f = [K / m0] 1/2. K - structure stiffness; m0 - reduced mass of the structure. In this calculation, a cantilever …
WebIt is seen, then, that by concentrating a mass equal to (33/140) m_{b} at the end of the beam, a more accurate value for the natural frequency of the cantilever beam is obtained compared to the result obtained by simply neglecting its distributed mass. In practice the fraction 33/140 is rounded to 1/4, thus approximating the natural frequency ...
