Four mass are fixed on a mass less rod as shown, the moment of inertia about the axis P in kg m2
1.02 kgm2
1.03kgm2
1.04kgm2
1.05kgm2
Moment of inertia of the four masses about the axis 'P',
I=2(0.4)2+5(0.2)2+5(0.2)2+2(0.4)2
I=4(0.4)2+10(0.2)2
I=1.04 kgm2
The moment of inertia of a system of four rods, each of length 'l' and mass 'm', about the axis shown is
