Multiple FBD Dynamics Problem

  1. Apr 27, 2008 #1
    1. The problem statement, all variables and given/known data
    The 4-kg uniform rod ABD is attached to the crank BC and is fitted with a small wheel that can roll without friction along a vertical slot. Knowing that at the instant shown crank BC rotates with an angular velocity of 6 rad/s clockwise and an angular acceleration of 15 rad/s^2 counterclockwise, determine the reaction at A.

    2. Relevant equations
    Newton's 2nd Law (Shown in FBDs)
    Acceleration and velocity kinematic equations
    aa = ab + aa/b
    va = vb + vc/b

    3. The attempt at a solution
    I've drawn FBDs and written out Newton's 2nd Law, but I'm at a loss on how to write the kinematics equations I need. I know that they involve a cross product, but I don't really know how to use them to make an equation that will come out to all i's and j's. Please help!

    Thank you.
