Friction circle radius= r sinθ
Where r = radius of shaft
θ= coefficient of friction.
So, answer D is correct.
Where r = radius of shaft
θ= coefficient of friction.
So, answer D is correct.

No, given answer is right.
Radius of friction circle is = coeff of frictions * radius of the journal.
Radius of friction circle is = coeff of frictions * radius of the journal.
