1. Homework Statement

What is the angular velocity magnitude of member BC?

Problem Figure Attached:

2. Homework Equations
V = w r
Va= Vb + Va/b


3. The Attempt at a Solution
I thought the problem would be simple as I could use v=w r to calculate the velocity and then use the equation of relative motion to calculate BC...But I am stuck trying to figure out the radius of the disc... Help please..

The full radius of the disk is not necessary. The radius at point C is given as .4 m. That with the angular speed gives the momentary velocity of point C. I'm assuming that the "4|_ 3" thingy is giving the slope of BC at that moment?
