Rotational MotionMedium

Question

Figure shows the variation of the moment of inertia of a uniform rod, about an axis passing through its centre and inclined at an angle θ to the length. The moment of inertia of the rod about an axis passing through one of its ends and making an angle θ = will be
                                                  

Options

A.0. 45 kg - m2
B.1.8 kg - m2
C.2.4 kg - m2
D.1.5 kg - m2

Solution

I = ML2 = 7.2
I = , I = = 1.8 kg - m2
