    Maybe I don't understand the problem, but, assuming [itex]\omega[/itex] is in the plane of the paper, and assuming B is the unlabelled vertex, aren't A and B merely in uniform circular motion about O?

    Omega is rotational speed. In our case the problem defines omega for shaft OA. B is just a point on a shaft. A and B are in uniform circular motion around a certain instantaneous axis of rotation. It's not "O". I'll try to get on a computer later so I can graph it...

    Looks correct to me.

    What does the solution manual say?

    Vb = 2.37 [m/s]

    I just wanted to make sure I didn't forget the material since I'm suppose to teach some students about it. Seeing a wrong answer to mine made me lift an eyebrow, but I'm glad my suspicion was verified it's not my mistake.

    It would be helpful if, in the future, you gave the text of the problem.

    That would explain that.
