[HELP] eccentric clamp (calculation)

[Wiplex]

Hello
I’m getting technical qualification for mechanical engineering and metals technology. I have to calculate an eccentric.
Given:
F1= 60N (at the hand gear)
F2=16KN (at the workpiece)
A1=80mm (length of the hand gear)

I can move the hand gear at max. 120°. Goal is the eccentricity of the eccentric. I calculated A2=0,63mm. I think it’s the throw.
I hope someone can explain what and how I have to calculate next or whether it’s wrong already.
Greetings

It would be nice to have a rough sketch. Where does the workpiece have to be? Fastened to the hand gear? (-> regard friction)

The gear has to be moved at 120° with power of 60N. The workpiece has to be clamped with 16KN.
Goal is the eccentricity of the eccentric therefore.
Greetings
