define Moment of Inertia about the co-ordinate axes of plane area shown in fig. Also find Polar Moment of Inertia.​

Answer 1

Answer:

Simply put, the polar moment of inertia is a shaft or beam's resistance to being distorted by torsion, as a function of its shape. The rigidity comes from the object's cross-sectional area only, and does not depend on its material composition or shear modulus.
