Can you explain *bending stress* what varies in simple bending theory?

While drawing a SFD stress changes linearly.

For BMD parbolically.

σ = My/ I,

So σ is directly proportional to y so there is a linear relationship.

I'm not understanding, so please anyone explain in detail.

For Bending Stress it varies linearly but the same will vary parabolically for bending moment.

Beam subjected to simple bending has linear variation of bending stress across any section from maximum compressive stress at innermost fiber to maximum tensile stress at outermost fiber.
