Follow-up Question

The area described in question 1(b) is filled by a flat metal plate with a surface
density σ = 3x. If the plate is secured to the y-axis by massless hinges,
calculate its moment of inertia about the y-axis.
[Note: the moment of inertia of a point mass, m is I = md^2
, where d is the
distance to the rotation axis under consideration].
