Q1. In a planetary gearbox, the sun gear with radius r1 is constant and the torque applied to the carrier, which rotates with a right angle w. Determine the rotational speed in an annular gearbox with a radius r, as well as the speed V of the point A lying on the circumference of the planetary gear.
