Dynamics: Angular Velocity Problem

  1. Feb 18, 2008 #1
    Hi there! I'm doing a particular question which is the angular velocity and I got stuck there halfway through.

    1. The problem statement, all variables and given/known data

    Find the angular velocity omega

    *see attachment

    Va = 1.4m/s to the left

    2. Relevant equations

    Vb/a = l * omegaAB

    Vb = Va + Vb/a

    3. The attempt at a solution

    I have split the whole Free Body Diagram into the translation and rotation, with the A fixed. And I have constructed the vector triangle. However, I couldn't find Vb/a because there is another unknown there.

    Anyone can help? Thanks very much. :)

    ur image is pending approval and hence i can't see it now.. and can't really help you. So.. why don't u upload your image to some image sharing site like: http://imageshack.us and provide the link here. It'll be faster than to wait for the image to be approved.

    Look at this. Your attempt was not good. I think that you can solve your problem now.
