Rotational MotionHard
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 : -
Options
A.
ML2
B.
ML2
C.
ML2
D.
Solution
Mass distribution about axis is not changed so MI remains unchanged.
