Cantilever Beam BM & SF diagram | why tapered Beam ?

In This video i will show you :-

why we provide cantilever tapered?

If only lateral loads are being applied (bending moment, shear forces) on cantilever, then our motive is to get same strength throughout its length against bending and shearing

Here, section modulous depends upon cross-section and directly proportional to cross-section.
As bending moment is maximum at its fixed end and zero at free end. So we keep maximum cross-section at its free end and minimum at free end (but not zero to avoid shearing).
We can keep same cross-section along its length but it is just waste of material and increasing weight.
So we reduce cross-section gradually (to avoid stress concentration) to save material and reduce weight.
