Help understanding why bending moment is integral of shear
I am aware of the basics of Euler-Bernoulli beam theory but there is one thing that I have never understood satisfactorily. Where $M$ is the bending moment, and $V$ the shear force:
$$\frac{dM}{dx}=V\,...

Shear Stress / Flexure Stress Formulas / Tables
Is there something similar to the Section Modulus in the Flexure Formula
$$\rho_{max} = \dfrac{M_{max}}{S}$$
where $S = \dfrac{I}{c}$ for shear stress formula?
So in
$$\tau_{max} = \dfrac{VQ}{IT}$$...
