THEOREM OF PERPENDICULAR AXIS

 THEOREM OF PERPENDICULAR AXIS

• According to the Theorem of perpendicular axis : I _z =I _x + I _y

• where I _x & I _{y =} moment of inertia of plain section about two mutually perpendicular axes x-x and y-y in the plain of section, I _Z moment of inertia of the section perpendicular to the plain and passing through the intersection of x-x and y-y axis.
