A 20 KN weight is suspended by two wires as shown in the figure. The length of each wire is 2 meter. The steel wire (E value 200 GPa) has an cross-sectional area of $$60 \times 10^{-6} m^2$$ and the aluminum wire(E value 70 GPa) has an cross-sectional area of $$120 \times 10^{-6} m^2$$, The stress in aluminum wire is

A

$$\frac{17}{102}$$ GPa

B

$$\frac{7}{120}$$ GPa

C

$$\frac{17}{120}$$ GPa

D

$$\frac{7}{102}$$ GPa
