For the given cross-sectional area: (1) Find the centroid and use it to calculate Ix , Iy and Ixy around the centroid axis (2) Based on Ix , Iy and Ixy in part (1), plot a Mohr’s circle and find Imax and Imin  (3) determine the Iu , Iv and Iuv with respect to new centroidal axes obtained by rotating the centroid axis, x, and y axes 45 degrees clockwise. Note: You must use the Mohr's circle to find Imax , Imin , and all parts of part (3)
