An epicyclic, gear train, as shown in Fig.15.26 is composed of a fixed annular wheel A having 150teeth. The wheel A is meshing with wheel B which drives wheel D through an idle wheel C, D beingconcentric with A. The wheels B and C are carried on an arm which revolves clockwise at 100 rpmabout the axis of A and D. If the wheels B and D have 25 teeth and 40 teeth respectively, find thenumber of teeth on C and the speed and sense of rotation of C.
