we r using various formulas to find moment of inertia according to the cross section but what is the actual need of that one where it applies ?

When the materials are subjected to load at any other location other than its central axis, the deformation it causes is bending. This causes stress in the materials. By estimating the bending moment and stress and knowing the breaking strength of the material, we will be able to decide the suitable cross section area and thickness to the material to withstand the load.
Any moving object also has MI. It continues to move unless some other force is applied on it. Ex Space satallite

moment of inertia can be defined as rotional inertia means if you want to rotate a body along an axis then you must provide enough torque to overcome this inertia which depends upon the mass of the object as well as on the axis distancefrom the object

The need for that is to know where the structure will fail on certain weight. Or shall we say locating the stress and the strain of the materials in their various locations.
