Question

what is polar movement of inertia??

Answer 1

polar .movement inertia as a measurement of a round bar's capacity to oppose torsion.

Answer 2

The polar moment of inertia, also known as second polar moment of area, is a quantity used to describe resistance to torsional deformation (deflection), in cylindrical objects (or segments of cylindrical object) with an invariant cross-section and no significant warping or out-of-plane deformation.
