### on critical speed derivation ### Critical speed Wikipedia

As the speed of rotation approaches the object's natural frequency, the object begins to resonate, which dramatically increases system vibration. The resulting resonance occurs regardless of orientation. When the rotational speed is equal to the numerical value of the natural vibration, then that speed is referred to as critical speed.

DERIVATION, CRITICAL SPEED FORM ULA Figure 2 shows a particle with mass m (represented as a dark circle) moving along a circular path of radius R with radial and tangential coordinates (r, t). To remain on a circular path it is necessary for a radial force Fr be applied; in practice this is supplied by friction.

More ### Maxwell-Boltzmann Distribution of Molecular Speeds

The molecules of gas move randomly in any direction. You may think that we have some idea about the molecular speeds of an ideal gas after understanding it's kinetic behaviour where we can find the average of the square of velocity of molecules and we can also find the rms-speed (root-mean-square-speed), however, this is not a complete solution to the distribution of molecular speeds.
