MOMENT OF INERTIA

this picture contains follwing scene. Diagram of a beam on its narrow edge supported at both ends. A man is walking on the straight beam. Diagram of a beam resting on its flat side supported at both ends. A man is walking on the straight beam and it is bending in the middle.  what does this diagram say to you????
ans: by changing the orientation of the beam ,bending of the beam can be avoided.Excess bending causes failure in order to use a number value for describing the bending of a particular geometry second moment of inertia is used.It is denoted by "I"
