Repeat problem $1$ assuming another material is modelled as $=400+300MPa$ and that it has the same $$ and $c_p$

You have a cylindrical block of annealed $4340$ which is $1\mathrm{.}5$ feet in diameter and $2$ feet high. You forge $($squeeze$)$ it down so it is $2$ feet in diameter.

a$.$ What is the height $($inches$)$ of the block after forging?

b$.$ What is the weight $($in short tons$)$ of the block?

c$.$ If the block was originally $72F,$ what is the temperature after forging? $($Hints: assume no volume dilation $,$ no heat transfer to the dies or environment, that the block stays cylindrical, Table $2\mathrm{.}2$ for $K$ and $n,$ textbook inside front cover for $$ and $c_p)$
