Write down the Bending equation of beam

Question

Accepted Answer

The bending equation of a beam relates the bending moment, the beam's cross-sectional shape, and the beam's material properties.

The bending equation is used to calculate the stress and deflection of a beam subjected to bending moments.
The equation varies depending on the type of beam (e.g. cantilever, simply supported) and the type of loading (e.g. point load, distributed load).
The general bending equation is M = sigma * I / y, where M is the bending moment, sigma is the stress, I is the moment of inertia, and y is the distance from the neutral axis.
The bending equation can be used to design beams that will not fail under expected loads.
Examples of applications of the bending equation include designing bridges, buildings, and aircraft.
