Option D is correct.
Composite shaft means Parallel working.
Composite shaft means Parallel working.

Here it is composite shaft so answer is k1+k3.

The Correct answer is D. Because it acts as a parallel shaft.

I think it is k1k2/(k1+k2).

For series = k1k2/k1+k2.
For parallel = k1 + k2.
But the case is not mentioned in question.
For parallel = k1 + k2.
But the case is not mentioned in question.

It is the case of parallel connection. So k1+k2.

It is K1 + k2.

It means is a parallel case.
Ans is k1+k2.
Ans is k1+k2.

The given answer is wrong.
The right answer is K1 + K2, as we know that any shaft whether stepped or normal if it fixed rigidly between the two supports, it acts like a parallel shaft. Because if apply torque anywhere on the shaft which is fixed between two rigid supports the angle of deformation of both the shafts is same.
