What is meant by the span of shaft?

Since critical speed depends on unbalanced mass about the axis of rotation. So option D is right.

On eccentricity, So, I think the answer is wrong.

Critical speed does not on eccentricity.

Critical speed of shaft does not depend on eccentricity, So, I think the answer is wrong.

In this case mass stiffness- gravity and deflection are the effect the critical speed of the shaft because take critical speed is equal to natural frequency omega n.

Critical speed of shaft doesn't depend on eccentricity, hence, the given answer is wrong.

The speed at which the deflection becomes infinity if eccentricity is away from the axis of rotation.
