GIVEN

The two pipes below are fixed connected to walls at $B$ and $D.$ Load $P$ has a magnitude of $2$ kips. $L=3ft.$ Segment $BC$ is made of a material with $E=18,000$ksi and has an outer diameter of $3$ in and wall thickness of $0\mathrm{.}25$ in$.$ Segment $CD$ is made of a material with $E=29,000$ksi and has an outer diameter of $4$ in and a wall thickness of $0\mathrm{.}5$ in$.$ Compute the external support reactions

Neglect the self$-$weight of the pipes.
