Question

The uniform disc shown in the figure has a moment of inertia of `0.6kg-m^(2)` arouond the axis that passes thorugh `O` and is perpendicular to the plane of the page. If a segment is cut out from the disc as shown, what is the moment of inertia of the remaning disc?

Answer 1

`I=(5)/(6)I_("total")=(5)/(6)(0.6)kg-m^(2)=0.5kg-m^(2)`
