Question

in a section undergoing pure bending, the neutral surface is subjected to :

Answer 1

hope the answer is right

Answer 2

Answer:

zero strain

for Example :- Case of sagging :-

Compression in top most fibre

Tension in bottom most fibre

So that strain diagram change from +ve to -ve and we get zero value before going in -ve zone

Conclusion:-

In Neutral axis every stresses become zero.
