How to create time varying inertia with Simscape Multibody?

Hi.
I want to create an object whose inertia changes according to time or position, and to see how the angular acceleration changes as the object rotates. For example, Figure 1.
So I made it like the Figure 2 and 3. Using a Simscape Multibody.
However, when we measured angular velocity, it showed constant acceleration as shown in Figure 4.
Which part do I need to modify to work as I intended?

EDIT: Variable solid blocks have been released in R2017b.
OLD ANSWER BELOW
That object has fixed moments of inertia, so it's expected that the angular acceleration stays the same.
More generally, variable-mass/inertia solids are not yet available in the latest version of Simscape Multibody. It is being considered for a future release. If you absolutely need it now, the First Generation block library will let you do this; however, those blocks are no longer maintained and there is functionality that isn't available in that library but is in the latest blocks.
