$4-8$ A frame made of timber carrying a load $P$ of $40kN$ is shown in Figure $4-8.$ The necessary properties of the timber are given in the Table $4\mathrm{.}8$ below. The crosssections of all members are $100mm100mm$ square.

$($i$)$ Compute the minimum values of $x$ and $y$ as shown in Figure $4-8$

$($ii$)$Verify whether the tensile stress in the tie $AC$ is within the permissible limit$.$
