Determine the moments of inertia Iu, Iυ and the product of inertia Iuυ for the rectangular area. The u and υ axes pass through the centroid C. Solve the above problem using Mohr’s circle. Hint: To solve, find the coordinates of the point P(Iu, Iuυ) on the circle, measured counterclockwise from the radial line OA. (See 10–19.) The point Q(Iυ, - Iuυ) is on the opposite side of the circle.
