I need to find if there is a torque on the support with 3 gears:
The Gear1 is forced to turn at 3w by an external device. Gear2 and Gear3 must follow.
The Attempt at a Solution
I drawn all forces to the support F1, F2, F3, F4 (I don't drawn all forces on gears) :
The support don't receive a torque only if d1=d2 ?
