Torque and Magnitude of Acceleration Question

  1. Dec 5, 2009 #1
    1. The problem statement, all variables and given/known data
    Question and data in attached diagram.


    2. Relevant equations
    Also in attached diagram.


    3. The attempt at a solution
    Again, in attached diagram.


    I can't establish the link between the rotation inertia and radius of the pulley into how that effects the acceleration of my 2 block system. I'm assuming you have to use the torque or angular momentum to work it in there?

    Write Newton's 2nd Law for the pulley. That will give you a relation between the tensions on the two sides.

    Torque = rxF ; F = T2-T1

    Therefore torque = rx(T2-T1), Thats the only thing i can think of...

    bump, I don't know how to use newtons 2nd law on the pulley :/.

    Torque corresponds to force, I to mass...

    (T2-T1)R = I α = I a/R
