(T hollow/T shaft)=(D^4-d^4)/D^4.

Here D= Diameter of Solid Shaft.

d=Diameter of Hollow Shaft = D/2.
(D^4-(D/2)^4)/D^4 =15/16.

@All.

It's 15/16.

Therefore the torsion = th/ts.

Th=15, ts=16.
Hence, torsion (t) =th/ts=15/16.

@All.

The question is ratio of the solid shaft to the hollow shaft not hollow shaft to solid shaft.

So the answer will be : 16/15.

Here torsion of solid shaft/torsion of the hollow shaft.
Ts/Th =16/15.

Th/Ts=(D^4-d^4)/D*Ds^3,
Ds is diameter of solid shaft,
put d=D/2,
we get 15/16,

Yes, the ratio of solid to hollow will be 16/15.
