Can anyone say the difference between bending & buckling?

Moment of inertia is m^4.

Column is always buckle to the axis of load about vertical direction.

Bending stress is inversely proportional to moment of inertia.

Cripling or buckling load is directly proportional 2 moment of iertia of a body. So if moment of inertia decreases buckling load also decreases. And at less load column will buckle.

What is a buckle?

The equation relating the buckling load and the moment of inertia is.
P=pi^2*EI/l.
So when I decreases the the load required for buckling also decreases thus gets deformed at a very low load.
Here l is the effective load.
P=pi^2*EI/l.
So when I decreases the the load required for buckling also decreases thus gets deformed at a very low load.
Here l is the effective load.

Area Moment of Inertia or we can say second moment of area is defined as the resistance to bending. So more the area moment of inertia, less will be the bending. Hence in the direction of bending the beam has minimum area moment of inertia.

Minimum moment of inertia because bending moment is inversely proportional to moment of inertia.

Bending stress = (moment*least lateral dimension)/moment of inertia.
F = M*B/I.
If bending stress(F) increases when M.I. Increases therefore it will buckle along minimum M.I.
F = M*B/I.
If bending stress(F) increases when M.I. Increases therefore it will buckle along minimum M.I.
