Homework Help: Moment of Inertia

  1. Oct 12, 2007 #1
    1. The problem statement, all variables and given/known data
    Picture1.png


    2. Relevant equations
    Moment of Inertia at one end of a bar = mL^2/3
    Sum of Moments around point A = Moment of Inertia at point A x angular acceleration (alpha)


    3. The attempt at a solution
    I have a few different equations with the variables replaced accordingly but I am having trouble finding the tension holding the bar up due to the mass on the other side of the pulley.

    Thanks!
    Emma

    Draw free body diagrams and use your equations for f=ma
