Centroid Problems Engineering Mechanics

Structural engineering depends upon a detailed knowledge of loads physics and materials to understand and predict how structures support and resist self-weight and imposed loads. In this case they are referred to as centroidal moments of inertia and are denoted as I cx for the inertia about the x-axis and I cy for the inertia about the y-axis.
