Assume that all gear blanks are solid circular cylinders unless specified otherwise.

For the planetary gear train shown in Fig. 1, N1 = 40, N2 = 50, N3 = 60, and N4 = 30 teeth. If the arm is rotating at 100 rpm in a clockwise direction as viewed from the left, what will be the speed and direction of the rotation of the output shaft connected to gear 4?
