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) `I_1=(Mb^2)/3` Moment of inertia of the plate about axis 2 (by taking rods perpendicular to axis 2)`I_2=(M1^2)/12`Moment of inertia of the plate 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=(M1^2)/3`.
