With reference to figure of a cube of
edge a and mass m, state whether the
following are true or false. (O is the
centre of the cube.)
(1) The moment of inertia of cube
about z-axis is, I_z = I_x + I_y
(2) The moment of inertia of cube
about z′ is, I_(z′) = I_z + ((ma^2 )/2)
(3) The moment of inertia of cube
about z′′ is, I_(z′) = I_z + ((ma^2 )/2)
(4) I_x = I_y
