A nonrotating rod, of the same mass (m) as the disk and length (l) equal to the disks diameter, is dropped onto the disk. They then both turnaround the spindle with their centers superposed. There is no slipping between the rod and the disk. What is the moment of inertia of the disk+rod system about the axis? What will be the speed of each of the following objects when it reaches the bottom of an incline if it starts from rest at a vertical height H and rolls without slipping?
