Calculating forces at pivots point in 4 bar linkages

[rbx]

First off all a big hello to all board members.

I'm designing a full suspension mountain bike the rear suspension use's a 4 bar design.
My question is..

I have found the reaction force at the rear axle, now i want to calculate forces in each pivot

My question is as follows..

Is the first moment calculated by multiplying the force at the axle X the distance to the center of curvature of the linkage?

Are the other moments calculated by multiplying the force X distance to their physical pivot?

i included a pic of the design

I am unable to relate the question to the diagram. What reaction force at the rear axle, and what pivot?
In general, you figure out the line of action of the force and the perpendicular distance from that to the pivot, then multiply the force by that distance.
