Let's study the Geometrical moment of inertia. In the second moment of the area, inertia is used instead of area. The second moment of area is closely related to the bending strength (stiffness) of the material. The inertia (= stiffness) that an object does not want to change when an external force that tries to bend occurs Because it has. Let's see Fig. 1!! When a load (F) is applied to the end..
