hi.
It refers to the bending of the beam or any structure upon the action of the arbitrary load. It is a degree of bending effect emerged when opposite force follows up on the beam. Normally a moment prevails when a force acts in perpendicular manner at a specific separation causing a rotational motion. When a moment acts on the beam and the beam tends to bend about its supports, then that moment is called as bending moment. It is expressed as the sum of the moments actingalong the beam.
Maximum bending moment in the beam occurs at the point of maximum stress. Also, maximum bending moment will be at the point where shear force changes its sign i.e., zero. Bending moment in a beam can be illustrated using bending moment diagram in which the values of bending moments are plotted in the vertical axis and the beam distance from the left in the horizontal axis.
Based on sign convention, bending moment is classified into two types.
1. Sagging/Positive bending
2. Hogging/Negative bending

it is a reaction induced in a structural element when an external force or moment is applied to the element causing the element bend the most common or simplest to structural element subjected to bending moments is the beam.
