What about if load acts in transverse and longitudinal axis, can anyone answer it? please.

Because at the neutral axis, there is no effect of load and therefore there is no stress at the neutral axis.

How can you say this?
Because this is only case of pure bending. Isn't it?

In loded beam the situation comes when stress goes either tension to compression or compression to tension. And the point comes when sum is equal to zero, if consider for whole line, so tht line would be as neutral axis.

The nuetral axis is an axis in the cross section of beam (a member resisting bending) and is geometrically centroid, because the bending stresses acting on an nuetral axis is zero.

We know that, bending stress=M/Z.
Aat neutral axis Z=0,
So bending stress is zero.
Here 'Z' is the second moment of inertia=I/Y,
and Y=D/2.

No load is acting that's why zero.

Because of shear stress maximum in N.A. So bending stress is min in N. A. And maxi in extreme fibre.

Because at the neutral axis No strain and No stress.

In the neutral axis, there is no force.
