Problem $2(30$ points$)$ For all members in the truss below: $=6\mathrm{.}0({10}^{-6})i\frac{n}{i}\frac{n}{}F,A=3i{n}^2,$ and $E=30({10}^3)ksi.$ The truss is loaded as shown in the sketch. Also, members AB and BC heat up $50F$ and there was a fabrication error on the member $AE$ such that member AE is $0\mathrm{.}25$ inches longer than intended. What is the horizontal displacement at E and the horizontal displacement at D $?$
