Homework Help: Angular velocity question

  1. May 21, 2007 #1
    1. The problem statement, all variables and given/known data
    Suppose we have a horizental massless tube.
    One end of the tube is welded to seomthing that rotates on an angular velocity of w1=(0, 1, 0), on the other end of the tube there is a disk, which rotates with an angular velocity of w2=(0, 0, 2)
    The system's angular velocity is w1+w2, and the kinetic energy of the system may be calculated, but I dont understand what is the meaning of the angular velocity w1+w2 in respect to the problem.
    Thank you.

    2. Relevant equations

    3. The attempt at a solution

    If you are asking for the resultant of the two angular velocities, then you have to add them vectorially, component-wise that is.
