Determine the tension supported in tie $\backslash ($ A $\backslash ).$ Assume $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash )$ are made of steel $(\backslash (\backslash$mathrm$\{$E$\}=200\backslash$mathrm$\{$GPa$\}\backslash ))$ and have square cross$-$sections. The crosssection of tie $\backslash ($ A $\backslash )$ is $7$ mm on a side and the cross$-$section of tie $\backslash ($ B $\backslash )$ is $10$ mm on a side. Answer in units of kN to $1$ decimal place.
