Aluminum Bar $( E = 70 \mathrm { GPa } , v = 0.33 )$

aluminum bar ( $( E = 70 \mathrm { GPa } , v = 0.33 )$ 0.33) of diameter 20 mm is stretched by axial forces P, causing its diameter to decrease by 0.022 mm. The load P is approximately:

A) $73 \mathrm { kN }$
B) $100 \mathrm { kN }$
C) $140 \mathrm { kN }$
D) $339 \mathrm { kN }$
