Critical load :The critical load of a column is that value of axial force that is just sufficient to keep the bar in a slightly deflected shape.

Slenderness ratio of a column : The ratio of effective length of the column (an axial compression member) to the minimum radius of gyration of the cross-sectional area is termed as slenderness ratio of the bar.

As it is a ratio so it has no units and of course it is dimensionless.

Note :

Radius of gyration is always the property of cross-section that is why the word cross-section is used with radius of gyration.
