The attempt at a solution

[itex]\frac{n2 - n6}{n5 - n6}[/itex] = [itex]\frac{- 18}{30}[/itex][itex]\frac{-28}{20}[/itex]

The answer is -30.9 rad/s (clockwise). The problem looks rather simple and I'm really not sure what I'm doing wrong.

Also if anyone knows where I can get more worked examples on these kinds of problems I'd really appreciate it!

Thanks in advance guys! (:

As in the previous problem, consider the frame co-rotating with arm 6. In this frame, [tex]
n_2' = n_2 - n_6
\\ n_5' = n_5 - n_6
[/tex] Then you can easily relate [itex]n_2'[/itex] and [itex]n_5'[/itex] in this frame, and then convert to [itex]n_2[/itex], [itex]n_5[/itex] and [itex]n_6[/itex].
