Current Attempt in Progress

The rigid bar ABC is supported by three bars as shown in the figure. Bars $(1)$ attached at A and $C$ are identical, each having a length of $L_1=151in.$ Bar $(2)$ has a length of $L_2=94in.$; however, there is a clearance of $c=0\mathrm{.}30in.$ between bar $(2)$ and the pin in the rigid bar at $B.$ There is no strain in the bars before the load $P$ is applied, and $a=58$ in$.$ After application of load $P,$ the tensile normal strain in bar $(2)$ is measured as $1060.$ What is the normal strain in bars $(1)?$
