Calculate the moment of inertia of a ring having mass `M`, radius `R `and having uniform mass distribution about an axis passing through the centre of the ring and perpendicular to the plane of the ring?

Text Solution

Verified by Experts

For a continuous body, moment of inertia is given by
`I=int(dm)r^(2)`
Because each element is at equal distance from the axis,
so `r=R:I=R^(2)intdm=MR^(2)`
