Multiple-choice question: For two figures as shown with the same area, what is the relationship between their moments of inertia about their respective horizontal centroidal axes z? ( ) Answer: D Hint: Extra rewards will be given to those who can explain the solution process; the answer can be seen there!
In Figure D, the cross-sectional areas of the three shapes are the same, and the distance of the cross-sectional distribution from the z-axis is (a) = (b) > (c)
