In solid mechanics, a bending moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend. [1] [2] The most common or simplest structural element subjected to bending moments is the beam. A bending moment describes the internal force that leads to bending of a structural element such as a beam due to loading. In easier words, a bending moment refers to the tendency of a structural element to deform due to external loading (self-weight, snow, wind, people etc.).
Bending Moment Types, Formula, Limitations, Bending Stress
A bending moment is a force normally measured in a force x length (e.g. kNm). Bending moments occur when a force is applied at a given distance away from a point of reference; causing a bending effect. In the most simple terms, a bending moment is basically a force that causes something to bend. Note that the moment increases with distance from the loaded end, so the magnitude of the maximum value of \(M\) compared with \(V\) increases as the beam becomes longer. This is true of most beams, so shear effects are usually more important in beams with small length-to-height ratios. Figure 3: Shear and bending moment diagrams. When a force is applied at the free end of a body which is fixed at another end, a moment of force arises in the body that can bend it. This moment is called the Bending Moment. One can observe such bending in the cantilever beam. The external force must be applied perpendicular to the length of the beam or rod which is known as the moment arm. Bending moments are produced by transverse loads applied to beams. The simplest case is the cantilever beam , widely encountered in balconies, aircraft wings, diving boards etc. The bending moment acting on a section of the beam, due to an applied transverse force, is given by the product of the applied force and its distance from that section..

We also provide equations and calculators for common beam configurations. Why Is Bending Moment Important? The design of structures incorporates the effects of loading. Bending moment at a section of a structural element is defined as the reaction developed in a structural element when an external force or moment is applied to the element that causes the element to be bent. Bending moment at a section of beam is calculated as the algebraic sum of the moment of all the forces acting on one side of the section. Mathematically, bending moment is the algebraic sum of the moments applied to the beam at any point along its length. It is calculated by multiplying the force acting on the beam by the distance from the beam's end to the point at which the bending moment is required. As its name implies, the bending moment occurs when a force is applied to a structural element (such as a column or beam), and that external force causes the element to bend and ultimately fail.

Bending moment function. By definition, the bending moment at a section is the summation of the moments of all the forces acting on either side of the section. Thus, the expression for the bending moment of the \(5k\) force on the section at a distance x from the free end of the cantilever beam is as follows: \(\begin{array}{l}
The bending moment is the algebraic sum of the applied load to the given distance from the reference point. Bending moments will also be caused due to the sum of applied moments from the reference point. The bending moment is an important part of the GATE CE syllabus. The bending moment is defined as the external load is applied in a beam element to bend. The bending moment is generated. The internal reaction loads in a cross-section of the structural elements can be resolved into a resultant force and a resultant couple for equilibrium the moment created by external force must be balanced by the couple.
