Let I be the moment of inertia of a uniform square plate about an axis AB that passes through its centre and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the centre of the plate and makes an angle 0 with AB. The moment of inertia of the plate about the axis CD is then equal to (a) I (c) I cos² 0 2 (b) I sin² 0 (d) I cos² (0/2)
