Is there any physical reason for this other than mathematical derivation ?
Thank you

Hollow Shaafts are stiffer than solid shafts of same materail because the polar moment of inertia of a hollow section can be much larger than the solid section of same area.
Polar Moment:-The polar moment of inertia is used to calculate the angular displacement of an object subjected to a torque. It can be defined as a quantity that predicts an object''s ability to resist torsion, in objects with an invariant circular cross section and no significant warping or out-of-plane deformation.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
