Rotational Motion · Moment of inertia

The moment of inertia of a square loop made of four uniform solid cylinders, each having radius R and length L (R<L)(R < L) about an axis passing through the mid points of opposite sides, is (Take the mass of the entire loop as M):
  1. (1)38MR2+712ML2\dfrac38 MR^2 + \dfrac{7}{12}ML^2
  2. (2)34MR2+16ML2\dfrac34 MR^2 + \dfrac16 ML^2
  3. (3)34MR2+712ML2\dfrac34 MR^2 + \dfrac{7}{12}ML^2
  4. (4)38MR2+16ML2\dfrac38 MR^2 + \dfrac16 ML^2
