One of the best video ,which I am using as example for my team member to explain Resonance /Critical speed

loved it! That's why high speed turbines are run at much higher speed than critical speed.

I use this to explain why an imbalanced and out of round tire vibrates until you hit 60 mph.

What about below critical speed?

the wobble will be lesser

The wobble is max at the critical speed, the further you are away from the critical speed the better.

brother i have a doubt , we know that centripetal force is proportional to square of velocity but in this experiment with decrease in speed causes more centripetal force to main the motion?

Unfortunately it is not enough, we need to take into account the forces of inertia, the elastic and damping reaction and then Apply D'Alembert to balance the forces and moments.

Critical shaft speed is when the rotation frequency matches the natural bending frequency of the shaft (based on shaft stiffness and mass. Safe operation is possible at higher speeds and lower speeds, but if you try to operate at or very near the critical speed, undamped resonance can lead to destructive events like the one in the video. This was a great demonstration of the fact that "too fast" is not the problem when it comes to dealing with critical shaft speed.

Its vibration, at critical speed the amplitude becomes infinite that's why this effect is observed
