A neutral axis is an imaginary axis above which the surface experiences tensile force and below the surface undergoes compression, whereas the neutral axis does not experience any force (the above condition is followed when the load is given from an upward direction).

Because there is neither compression nor tension at centre.

At neutral axis there there will be no effect applied of applied load.

Neutral axis is the line interaction with neutral layer with transverse axis. In above neutral axis the layers are compressed and below the layers are tensed. There is no load acting on neutral axis. So bending moment on the neutral axis is zero.

Bending stress is zero because no effect on the neutral axis due to applied loads.

AT neutral axis no develop the stress.

There is no load acting on neutral axis. So bending moment on the neutral axis is zero.

No load is acting at the NA So BM will be zero.

Depending on the material used (if elastic), when bending a beam, one surface eventually stretches due to tension while the surface opposite compresses without damaging or breaking the beam due to the fact that the proportional limit is not exceeded which implies that, there exist a neutral axis or zero stress.

Bending stress is zero, because the effect of load is zero.
