The components of stress in a body under plane stress condition, in the absence of body forces, is given by:

$\sigma_{x x}=A x^{2} ; \sigma_{y y}=12 x^{2}-6 y^{2}$ and $\sigma_{x y}=12 x y$ The coefficient, A, such that the body is under equilibrium is__________________ (accurate to one decimal place).
