AB is a stick half of which is wood and the other half steel. `I_(A)` is moment of inertia about an axis passing through A and perpendicular to the length . `I_(B)` is moment of inertia about an axis passing through B and perpendicular to the length. Then

`I_(A)=I_(B)`

`I_(A)gt I_(B)`

`I_(B)gt I_(A)`

we can not say
