Write theorem of perpendicular and parallel axes.​

Answer»

Perpendicular axes theorem : If I_x and I_y are the MOMENT of inertia about two perpendicular axes of any BODY the moment of inertia I about THIRD perpendicular AXIS is the sum of two moment of inertia.i.e. I_z = I_x + I_yParallel axes theorem : The moment of inertia I about an axis parallel to the axis through centre of mass C.M. is the sum of moment of inertia about C.M. and product of total mass M and SQUARE of perpendicular distance r between two axes concerned.i.e. I_CD = I_AB + M r²  where AB║ CD
