The cross section of the bar shown is symmetric about either the x or y axis.

(a) Determine d so that the origin of the coordinate system, point O, is positioned at the centroid of the area.

(b) Determine the area moment of inertia about the x axis.

(c) Determine the area moment of inertia about the y axis.

Hint: If you carried out some of the exercises from Section 7.1, beginning on p. 445, you may have already solved Part (a) of Probs. 10.46 and 10.47.
