Relevant Equations

Determine the force created due to the compression of the plier

The question is to determine the force in the small opening, delivered from the 250 N on both sides of the plier.
i tried multiple things but can't get the answer right. Anyone that could help me?
This is my work so far:

We cannot help you until you show your work so far. Please post your FBD and show your calculations that you have tried. Thanks.

EDIT -- it looks like you've gone back and posted your initial calculations. Thank you.

Your diagram omits the second fulcrum, the one 70mm from the workpiece.
This is an essential part of the mechanism.

This would be an excellent place to employ the Principle of Virtual Work.

Yes, and there are two more pivots 230mm from the work that the force diagram appears to treat as rigid.
