For that same section, the larger principal second moment of area is nearest to
Answer: D
Using \( I_{1,2} = (I_{xx}+I_{yy})/2 \pm \sqrt{((I_{xx}-I_{yy})/2)^2 + I_{xy}^2} \), the mean is \( 6 \times 10^6 \) and the radius is \( \sqrt{2^2 + 2^2} = 2.83 \times 10^6 \), giving \( 8.83 \times 10^6 \) mm\( ^4 \). The smaller principal value is \( 3.17 \times 10^6 \).
