Two aeroplanes with the same specification each that has an engine rotates at 2000 rpm with the moment of inertia for all rotating parts is 420 (kg)(m^2). The engine rotates anti-clockwise when viewed from the front. One of the aeroplanes turn to the left and the other turn to the right. Compare the magnitude and effect of the gyroscopic action resulting on the plane if the turning radius is 2000 m at a speed of 2000 km/h.

In the planetary gear train shown in Figure Q2, the annulus A
rotates at 300 rpm about the axis of fixed wheel S which has 80
teeth. The armed spider (arm) is driven at 180 rpm. The annulus is
connected to input shaft whereas the arm is connected to the output
shaft. If the efficiency of gear system is 98% and input torque is
100 Nm, identify the following information regarding these problems
(i) The number of teeth on planet...
