For the steel truss $(E=29{10}^6)$ and loading shown, determine the deformations of members $AB$ and $AD,$ knowing that their crosssectional areas are $4\mathrm{.}0i{n}^2$ and $2\mathrm{.}8i{n}^2,$ respectively. It is given that $P=34$kips.

The deformation of member $AB$ is $-$ in$.$

The deformation of member $AD$ is $$ in$.$
