(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Bars BC and AB and dish OA are attached by a pin like in the picture. The dish has a constant angular velocity [itex]\omega\_{0}[/itex]. Find the angular acceleration of bars BC and AB.

2. Relevant equations

Relative Motion Equations:

v[itex]_{b}[/itex]=v+[itex]_{A}[/itex]v[itex]_{A/B}[/itex]

a[itex]_{B}[/itex]=a[itex]_{A}[/itex]+[itex]\alpha_{A}[/itex]Xr[itex]_{B/A}[/itex]-[itex]\omega^{2}[/itex]r[itex]_{B/A}[/itex]

3. The attempt at a solution

So far, I have this written down:

V[itex]_{A}[/itex]=[itex]\omega[/itex]r

a[itex]_{A}[/itex]=V[itex]_{A}[/itex][itex]^{2}[/itex]/r=[itex]\omega^{2}[/itex]r

a[itex]_{B}[/itex]=[itex]\alpha_{BC}[/itex]Xr[itex]_{BC}[/itex]-[itex]\omega_{BC}^{2}[/itex]r[itex]_{BC}[/itex]

Still just fumbling over these equations. Any help is appreciated.
