(c) Notice in disk integration the area was rotated around the same axis that the area was integrated on. In other words, the axis the area touched was the axis of rotation. In shell integration, it is the opposite. Notice that the area is touching the x axis and the solid is rotating around the y axis.

#### Solved: 5. Two Disks Are Rotating About The Same Axis. Dis ...

And so we could view this as 16/2 minus 1/2, which is equal to 15/2. So this is equal to 15/2 times pi. Or another way of thinking of it is 7 and 1/2 times pi. But this is a little bit clearer. So we're done. We found our volume not rotating around the x-axis, but rotating around the y-axis, which is kind of exciting.

#### How will the angular momentum be conserved when two ...

The rotating systems shown in the figure differ only in that the two identical movable masses are positioned a distance r from the axis of rotation (left), or a distance r/2 from the axis of rotation (right). If you release the hanging blocks simultaneously from rest, A) the block at the left lands first. B) both blocks land at the same time.
