A Titanium Bar (E = 100 GPa, V = 0 $1400 \mathrm{~mm}^{3}$

A titanium bar (E = 100 GPa, v = 0.33) with square cross sec- tion (b = 75 mm) and length L = 3.0 m is subjected to tensile load
P =900 kN. The increase in volume of the bar is approximately: (A) $1400 \mathrm{~mm}^{3}$
(B) $3500 \mathrm{~mm}^{3}$
(C) $4800 \mathrm{~mm}^{3}$
(D) $9200 \mathrm{~mm}^{3}$
