Two thin disks are attached as shown to the right. The angle θ = 22.5°, and the masses and radii of the disks are listed in the table below.
Disk Radius(cm) Mass(kg)
A 21.3 0.926
B 6.70 0.429
What is the moment of inertia of this composite object about an axis perpendicular to the screen, through point p?
