Do bending moment and shear forces are dependable on a beam's cross sectional area?

They do not.

The bending moment is the integral of the shear force curve, and the shear force curve is the integral of the load curve of the beam.

Very much thank you to you sir! I was wondering that we're not given any of those cross sectional details when we're asked to draw SFD and BMD. So that's a kind of a hidden tip ;)
