What is the formula for critical speed?
The critical speed of a shaft can be found using the following formula.
Where
r represents the distance of the geometric centre from the bearing axis
e represents the eccentricity, i.e., the distance between the geometric centre and the centre of gravity.
Let us know the key assumptions that were made while deriving the above-mentioned relation for the critical speed of the shaft to understand the concept better.
