Question

in simple beams the bending moment has a maximum magnitude. at the point of the load application wherever the shear passes through zero always at midspan at the supports

Explanation:

The relationship between shear force and bending - moment in beams is such that the bending - moment has a maximum or minimum where the shear force passes through zero. This is based on the differential relationship $V=\frac{dM}{dx}$, where $V$ is the shear force and $M$ is the bending - moment. When $\frac{dM}{dx}=0$ (shear force $V = 0$), the bending - moment $M$ has an extremum.

Answer:

wherever the shear passes through zero
