We say BM is constant for this.

Shear force is zero, i.e Result BM either max or min n.

If In a cantilever beam, At free end doesn't any load whereas fs is zero and bmd must be zero. How you say that, Will you please explain?

In magnitude numerical value will be maximum.
But when we consider negative sign so that it can be maximum or minimum.
Because dM/dX=0 so, M can be max or min.

Answer is maximum or minimum? Please explain.

Yes, @Syed Irfan.
My argument is also that only.
At the max BM SF will be zero. Not possible reverse side like where SF is zero BM is max.

No, it will not be maximum because bending moment is maximum at a point where shear force is zero only at a point not along the section.

Like cantilever, and subjected to bending moment at the free end then there is no shear force (s.f.d is a straight line), and b.m.d is rectangular.

You are right @Jay.

Numerically we can't get the maximum value we have to see the loading condition.
