Help with this mechanism (acceleration with graphic method)

AI Thread Summary
The discussion centers on a user's difficulty in determining acceleration using a graphical method for a specific mechanism. The user has already created a speed diagram but is unsure about the accuracy of their acceleration diagram, particularly regarding the acceleration of point "G." They seek clarification on the direction of rotation, confirming it is counterclockwise for link AB. Other participants encourage sharing the velocity work to provide better assistance. The conversation emphasizes the importance of accurately representing both speed and acceleration in mechanical diagrams.

Find the aceleration of each link in the mechanism
Relevant Equations
W = V´2/r
Hi guys!
I have problems with this mechanism...finding the aceleration with graphic method.

I already have drawn the speed diagram and the values of all of them.

But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the acceleration of "G"

Thank you.
Could you show us your work on velocities?
