 ### Lecture 15: Determination of Natural Frequencies and Mode ...

The frequency of vibration of a conservative system vibrating about an equilibrium position has a stationary value in the neighborhood of a natural mode. This stationary value, in fact, is a minimum value in the neighborhood of the fundamental natural mode. Rayleigh's method ### critical speed equation derivation of ball mill

The derivation of the heat equation is based on a more general principle called the conservation law. It is also based on several other experimental laws of physics. We will derive the equation which corresponds to the conservation law. Then, we will state and explain the various relevant experimental laws of physics. ### SOLUTIONS TO THE HEAT AND WAVE EQUATIONS AND THE ...
