Two shafts A and B under pure torsion are of identical length and identical weight and are made of the same material. The shaft A is solid and the shaft B is hollow. We can say that
shaft B is better than shaft A
shaft A is better than shaft B
both the shafts are equally good
Answer: Option

May be but here two shafts under pure torsion so solid shaft better than hollow shaft because it will resist more torsion than hollow shaft.

If two shaft are in equal weight then the cross-section of the hollow shaft remains the shear stress and transmitted torque.

The question didn't determine the point of comparison between the two shafts.

Shaft B is better probably because it saves cost and material used.

Here B can transmit more power/torque than A.

Hollow shaft can bear more Shear Stress.
