4. (a) State why the moment of inertia is always positive, and why the moment of inertia about the axis passing through the centroid is always smaller than that about any other parallel axes. (10 pts) (b) Locate the centroidy of the beam's cross- sectional area. Determine the moments of inertia and products of inertia of this area about the x and y axes as well as u and v axes. (15 pts) 200 mm IT 30 mm 80 mm 80 mm
