Question

State two application of polar moment of inertia

Answer 1

Answer:

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.[1] It is a constituent of the second moment of area, linked through the perpendicular axis theorem
