Please answer the given problem and show the complete solution. Thank you very much! Determine the largest weight W which can be supported by the two wires shown. The stresses in wires AB and AC are not to exceed $130$ MPa and $110$ MPa, respectively. The cross$-$sectional areas of the two wires are $400$mm$^2$ for wire A B and $400$mm$^2$ for wire AC$.$ Answer must be in kN$.$ Given A$=30^$ and B$=60^.$

$1-$ Determine the largest weight, W$,$ which can be supported by the two wires.

$2-$ What is the cross$-$sectional area of bar BF$?$

$3-$ What is the force in wire AB$?$

$4-$ What is the force in wire AC$?$
