Homework Help: Angular Acceleration of at woods machine

  1. Feb 28, 2008 #1
    1. The problem statement, all variables and given/known data

    An Atwood's machine consists of two masses, m1 and m2, which are connected by a massless inelastic cord that passes over a pulley, Fig. 10-70. If the pulley has radius R and moment of inertia I about its axle, determine the acceleration of the masses m1 and m2 (a), and compare to the situation in which the moment of inertia of the pulley is ignored (a0). [Hint: The tensions FT1 and FT2 are not necessarily equal.] (Use m_1 for m1, m_2 for m2, R_0 for R0, and g and I as appropriate.)

    a= _________

    a(0)= _________

    2. Relevant equations

    T = I * a(angular) = F*d*sin90

    3. The attempt at a solution


    Attempt at Solution: I was trying to sum the forces and use Torque but I have NO idea what Torque is or what the value of the normal force is. :(

    Before you mark this as solved, does anyone know how to find the tension on each side of the pulley?
