I think cast iron has less Poisson ratio than steel. We know that Poisson ratio =lateral strain/linear strain. Due to this castiron has more carbon percent than steel. So, the lateral strain will be less compare to steel.

Option A is the correct answer.
Clay 0.30-0.45,
Stainless steel 0.30-0.31,
Steel 0.27-0.30,
Cast iron 0.21-0.26.
Clay 0.30-0.45,
Stainless steel 0.30-0.31,
Steel 0.27-0.30,
Cast iron 0.21-0.26.

Poission's ratio of:-
Cast iron:-0.23 to 0.27.
Steel :-0.25 to 0.33.
"This is correct answer".
Cast iron:-0.23 to 0.27.
Steel :-0.25 to 0.33.
"This is correct answer".

C.I -> 0.23-0.27.
MILD STEEL -> 0.25-0.33.
AL -> 0.34.
CORK -> 0.34.
CONCRET -> 0.15.
POLYMER -VE.
MILD STEEL -> 0.25-0.33.

Poisson's ratio of CI is 0.23 to 0.27 (refer chapter 6-Elastic constants page no.93 Khurmi Gupta).

In R.s.Khurmi. 0.23-0.27.
In R k.Jain. 0.25-0.33.
Which is correct option? Please tell me.
In R k.Jain. 0.25-0.33.

In (R S Khurmi) Book, it's,
For Steel : 0.22 to 0.25.
And for CI : 0.25 to 0.33.
For Steel : 0.22 to 0.25.
And for CI : 0.25 to 0.33.

Cast iron is brittle than steel so its poisons ratio will be less than steel.
