The moment of inertia of a thin uniform rod of length L and mass M about an axis passing through a point at a distance of 1 / 3 from one of its ends and perpendicular to the rod is

Options

  1. AM L² 12
  2. BM L² 9
  3. C7 M L² 48
  4. DM L² 48

Correct answer

B. M L² 9

Step-by-step solution

I_ CM = M L² 12 (about middle point) I=I_ CM +M x² array l = M L² 12 +M ( L 6 )² I= M L² 9 array
