It is 16/15.

Prachi said:   6 years ago
Yes, it is 16/15 because it has asked for the ratio of solid to the hollow shaft.

Yes, the ratio of solid to hollow will be 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,

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

@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.

Therefore the torsion = th/ts.

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