# Vectors (magnitude and direction) for forces in this diagram

### Mardoxx

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: $$mr\dot{\omega} = mr\ddot{\theta}$$
Radial component: $$mv^2 = mr\omega^2$$

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!
