Answer:
When a beam is subjected to a bending moment, the strain in a layer is Directly proportional to the distance from the neutral axis.
Explanation:
The neutral axis is an axis in the cross-part of the beam where there is no longitudinal strain or stress.
Overall bending of beam produces both bending and shear force (there is no shear while bending is steady). Bending strain proportional to its distance to the neutral axis is a supposition and it is material to thin beam, for example where the strain from shear can be ignored. This is communicated as "segment stays plane before and after deformation".
