The truss shown is subjected to forces $\backslash (\backslash$mathrm$\{$P$\}=62\backslash$mathrm$\{$kN$\}\backslash ),$ the length $\backslash ($ L $\backslash )$ divided into equal spaces, and $\backslash (\backslash$mathrm$\{$H$\}=1\mathrm{.}9\backslash$mathrm$\{$~m$\}\backslash ).$ If the resistance of bar $1$ is $198$ kN ; Determine the maximum length $($in meters$)$ of the reinforcement so that the resistance of said bar is not exceeded.
