Question

state and prove theorm of perpendicular axis above moment of enertial​

Answer 1

Answer:

If Ix, ly and lz are the moments of inertia of the plane lamina about the axes OX, OY and OZ respectively, then according to the theorem of perpendicular axes, Iz = Ix + ly. This theorem is appropriate only to the planar bodies. Bodies which are flat with very less or insignificant thickness.

Explanation:

Answer 2

The theorem states that “the moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of the moments of inertia of the lamina about any two mutually perpendicular axes in its plane and intersecting each other at the point where the perpendicular axis passes though it.”
