Cast iron- 0.31-0.34.
Shivam bihar said:   8 years ago
Cast iron 0.23-0.27 and steel-0.25-0.33.

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.

A is the correct answer.

Poission's ratio of:-

Cast iron:-0.23 to 0.27.
Steel :-0.25 to 0.33.
"This is correct answer".

In R.s.Khurmi. 0.23-0.27.
In R k.Jain. 0.25-0.33.

Which is correct option? Please tell me.
Nitin said:   8 years ago
Answer should be "A".

Here C.l. =0.23 to 0.27 and steel 0.25 to 0.33.
