With reference to figure of a cube of edge a and mass m, state whether the following are true or false.

Q: With reference to figure of a cube of edge a and mass m, state whether the following are true or false. (0 is the centre of the cube.)

Numerical

(a) The moment of inertia of cube about z-axis is I_z = I_x + I_y

(b) The moment of inertial of cube about z’-axis is I’_z = I_z + ma²/2

(d) I_x = I_y

Ans: (a) , (b) & (d)
