Question

A symmetric lamina of mass M consists of a square shape
with a semicircular section over of the edge of the square as
shown in figure. The side of the square is 2a. The moment of
inertia of the lamina about an axis through its centre of mass
and perpendicular to the plane is $1.6M{a}^2.$ The moment of
inertia of the lamina about the tangent A B in the plane of the
lamina i s................

Answer 1

$4.8M{a}^2$
