every solution chegg has sent me$,$ it says to refresh. Please help, i can not see the solution. The following rod of modulus $29,000$ksi is loaded as shown. The lengths are $L_1=17in,L_2=15in,$ and $L_3=15in.$ The forces are $P_1=0\mathrm{.}7$kip,$P_2=2\mathrm{.}0$kip, and $P_3=$

$2\mathrm{.}1$kip. The areas are $A_1=0\mathrm{.}08i{n}^2,A_2=0\mathrm{.}06i{n}^2,$ and $A_3=0\mathrm{.}06i{n}^2.$ Determine the displacement at the location of $P_3$ in inches $($positive rightward$).$
