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

Explanation

Moment of inertia of the plate about axis 1 (by taking rods perpendicular to axis 1)
`1_(1)= Mb^(2)//12`
Moment of inertia of the plate about axis 2 (by taking rods perpendicular to axis 2)
`I_(2) = M l^(2) //12`
Moment of inertia of the plate about axis 3 (by taking rods perpendicular to axis 3)
` l_(3) = (Mb^(2))/(12)`
Moment of inertia of the plate about axis 4(by taking rods perpendicular to axis 4)
` I_(4) = Ml^(2)//3`
