In Fig. find moment of inertia of a plate having mass `M`, length `l` and width `b` about axes `1, 2, 3` and `4`. Assume that `C` is the centre and mass is uniformly distributed.
`

Explanation

Moment of inertia the plate about axis `1` (by taking rods perpendicular to axis`1`)
`I_(1)=(Mb^(2))/3`
Moment of inertia of the plate about axis `2` (by taking rods per pendicular to axis `2`
`I_(2)=(Ml^(2))/12`
Moment of inertia of the plane about axis `3` (by taking rods perpendicular to axis `3`)
`I_(3)=(Mb^(2))/12`
Moment of inertia of the plate about axis `4` (by taking rods perpendicular to axis `4`)
`I_(4)=(Mb^(2))/3`
