What is z?

Is it section modulus?

Z may be behaved as moment mill of area.

Z required = M/bending stress.
Max. Bending stress = 0.66*250 = 165n/mm2.

Always z required <zavailable.
When bending moment increases existing zavailable then extra plate provided for covering to it.

Hence plate area calculate .
Zrequired-zavailable /h.
