Two identical rings, each of mass m and radius R, have mutually perpendicular planes and are welded at O. Find the moment of inertia about the axis through P perpendicular to the page.
Options:
Answer:
D
Solution:
Use the parallel-axis theorem for both perpendicular rings about the axis through P.
Adding the two ring contributions gives 11.5mR².
Hence option D.
