The moments and product of inertia of an L4 × 3 × -in. angle cross section with respect to two rectangular axes x and y through C are, respectively, x= 1.33 in4, y = 2.75 in4, and xy<0, with the minimum value of the moment of inertia of the area with respect to any axis through C being min = 0.692 in4. Using Mohr’s circle, determine (a) the product of inertia xy of the area, (b) the orientation of the principal axes, (c) the value of max.
