Homework Help: Vectors (magnitude and direction) for forces in this diagram

  1. Apr 18, 2010 #1
    1. The problem statement, all variables and given/known data
    I have x, y, theta, omega and alpha at any given t so that's not a problem if they're needed.
    I need magnitude and direction for the forces in the diagram to show them in my model.

    2. Relevant equations
    Transverse component: [tex]mr\dot{\omega} = mr\ddot{\theta}[/tex]
    Radial component: [tex]mv^2 = mr\omega^2[/tex]

    3. The attempt at a solution
    Code (Text):
    radial.axis = v.vector(-x,5-y)/(v.mag(v.vector(cos(2.1*5*s[1]**2),sin(2.1*5*s[1]**2))))
        transverse.axis = -v.vector(x,y)/(v.mag(v.vector(cos(2.1*5*alpha),sin(2.1*5*alpha))))
    but that doesn't work properly, also I'm missing the mg component down....
    help? :P

    Thanks in advance!
