    How to find torque on planet carrier

    I have the following data in an epicyclic gear train:

    Angular speed on ring = 1500 rpm, teeth on ring = 30
    Angular speed on sun = 3200 rpm, teeth on sun = 10
    Angular speed on carrier = 1925 rpm, teeth on planets = 10

    (The ratios of teeth are for simple calculation assumed 3: 1: 1 among ring, sun and carrier.)

    Now,

    torque on ring = 190 Nm
    torque on sun = 50 Nm

    How do I find the torque on the planet carrier?

    Please help me!!
