A thin rod of length L and mass M is bent at its midpoint into two halves so that the angle between them is 90°. The moment of inertia of the bent rod about an axis passing through the bending point and perpendicular to the plane defined by the two halves of the rod is : |
\(\frac{\sqrt{2}ML^2}{24}\) \(\frac{ML^2}{24}\) \(\frac{ML^2}{12}\) \(\frac{ML^2}{6}\) |
\(\frac{ML^2}{12}\) |
Distribution of masses about axis of rotation remain unchanged whether it is straight or bend. I = \(\frac{ML^2}{12}\) |
