The truss is made from five members, each having a length of $4$ m and a mass of $\backslash (7\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}\backslash ).$ If the mass of the gusset plates at the joints and the thickness of the members can be neglected, determine the distance $\backslash ($ d $\backslash )$ to where the hoisting cable must be attached, so that the truss does not tip $($rotate$)$ when it is lifted.
