Calculating forces at pivots point in 4 bar linkages

    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
