A thin rod of length LL and mass MM is bent at its midpoint into two halves so that the angle between them is 90∘90^{\circ}. 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

Options

  1. A2ML224\frac{\sqrt{2} M L^2}{24}
  2. BML224\frac{M L^2}{24}
  3. CML212\frac{M L^2}{12}
  4. DML26\frac{M L^2}{6}

Correct answer

C. ML212\frac{M L^2}{12}

Step-by-step solution

Distribution of masses about axis of rotation remain unchanged whether it is straight or bend. I=ML212\frac{M L^2}{12}
