Problem 4.4 Determine the moments of inertia and the products of inertia about the centrodial axes of the shaded area shown in Fig. P4.4, where a = 1 in. Find the centroid polar moment of inertia. The mass center of the shaded area is at C . C a a a a 3 a x y 1 2 3 Figure P4.4: Problem 4.4 Solution % ICxx = b h^3/12; ICyy = h b^3/12 % upper rectagle 1 A1 = 3*a^2; IC1xx = (3*a)*a^3/12; IC1yy = a*(3*a)^3/12;
