Eq is

P=(π^2EI)/l^2 K=√(I/A) where k is radius of gyration

Then substitute I/A = k^2
Then eq will be,

P=(π^2EK^2A)/L^2.
So buckling load is directly proportional to the radius of gyration.

Vertical member will have two moment of inertia along x and y direction so the column tends to buckle least moment of inertia.

When the body tends to bucklLong column only can fail by buckling (with a certain condition).

l/r > 97 (must for long column).

So least r required. The radius of gyration created.

Minimum radius side has low bending stresses and hence the member tries to buckle towards the side which provides less resistance to it.

It may be least radius of gyration and minimum moment of inertia.
