Approach Force Analysis using the Graphical Method Paper

The assignment requires you to do Position, Velocity, acceleration and force analysis to a 4 bar linkage with a slider. We are working on a window slider mechanism (similar to crank slider). I have completed the Position, Velocity and acceleration Analysis. But I am struggling with the force analysis.

Note: I look online extensively but couldn’t find any good solution. So please DON’T ACCEPT THE QUESTION UNLESS IF YOU CAN SOLVE IT 100% CORRECTLY AND THE SAME METHOD THE PREVIOUS WORK HAS BEEN DONE (attached).

I am looking for it ti be solved in the same method as the other analysis has been done and the chapter handout
