In an epicyclic gear train shown in Fig 15.46 the \(\operatorname{arm} A\) is fixed to shaft \(S\). The wheel \(B\) having 90 teeth rotates freely on shaft \(S\) and wheel \(F\) with 135 teeth is separately driven. If arm \(A\) runs at \(240 \mathrm{rpm}\) clockwise and wheel \(F\) at \(120 \mathrm{rpm}\) in the same direction, find

(a) number of teeth on wheel \(C\), and

(b) speed of wheel \(B\).
