If the drawn pulley also receives the inertia moment Jc of a load then :

R = Gearbox ratio
➜ NB:
The inertia of a gearbox is calculated stage by stage, each gearwheel
being considered as a cylinder.
In practice the calculation of the first two gears, even the first one only,
will give a sufficient approximate value.
