Torque required

    Torque required!!!


    Problem Statement:

    A flywheel with Moment of Inertia I, and rpm w1 is rotating. It has a shaft at is center which is attached to a gearbox (1:100) at one end. The output shaft of the gearbox will rotate at w1 x 100. The other end of the shaft of the flywheel will rotate at w1.

    Now, I need to stop the flywheel in 't' sec. Will the torque required to stop the flywheel will be the same at both the ends?

    Hi Vaibhav! Welcome to PF! :smile:

    (have an omega: ω :wink:)
    Yes, for a particular acceleration α, torque = Iα …

    I is the same, so the torque will be the same whichever end you apply it. :smile:
