Homework Help: Complex mechanics/dynamics problem

  1. Mar 2, 2012 #1

    So this is the problem. Relevant equations should be:

    Aa = Ab + Aa/b
    Va = Vb + Va/b

    and vector notation:

    Aa = Ab + ω' x r + ω x (ω x r) + 2ω x Vrel + Arel

    I have no attempt at this because I am currently working on it and really have no idea if I am going in the right direction.

    Can anybody help?
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    Is the distance r1 variable? I presume that the distance r is considered as a driving motion, but how does changing r cause anything else to change? It looks like r could change without requiring motion anywhere else. Something is quite unclear about this mechanism.

    Where are a and b? (the lower case letter points)?
