Pligquestion

The two$-$segment statically indeterminate bar in the following figure has a constant cross$-$sectional area $A=0\mathrm{.}8i{n}^2.$ It is made entirely of material that has elastic, perfectly plastic behaviour with oy $=36$ksi and $E=3010$ksi. If P$=45$kip is applied to the bar and then removed

$($d$)$ A two$-$segmenivan$*$ periectly$-$plastic material.

a$)$ Determine the residual stress in each segment $$

b$)$ Find the permanent deformation at point $B.$

c$)$ Determine the smallest load $P$ needed to cause segment CB to yield. $$
