M = bending stress x Section Modulus.
So, M is proportional to b when d is constant,
and M is proportional to underoot d when b is constant.
So, M is proportional to b when d is constant,
and M is proportional to underoot d when b is constant.

And if d=constant.
Then Be is directly proportional to M.
Then Be is directly proportional to M.

M/I = f/y.
I = bd3/12.
M is proportional to d^2.
So, d is √ M.
I = bd3/12.
M is proportional to d^2.
So, d is √ M.
