Question
The moment of inertia of a rod about an axis through its centre and perpendicular to it is 
ML2 (where M is the mass and L is the length of the rod). The rod is bent in the middle so that the two half make an angle of 60o. The moment of inertia of the bent rod about the same axis would be : -

A.
ML2
ML2B.ML2
ML2C.
ML2
ML2D.
Solution
Mass distribution about axis is not changed so MI remains unchanged.
