Question

Find moment of inertia of a square plate of mass 'm', side 'a' about an axis passing through its one end and perpendicular to the plane.

Answer 1

Moment of Inertia of a square plate of side ‘a’ and mass ‘m’ about an axis passing through its centre and perpendicular to its plane is, I = (1/6)ma²

 

Thus Moment of Inertia = ma²/6 + ma²/2 = (2/3) ma²
