    1. The problem statement, all variables and given/known data

    How do we derive the total spring constants of different mass spring systems

    2. Relevant equations

    F= kΔx

    3. The attempt at a solution

    I have just realised this is similar to this thread
    https://www.physicsforums.com/showthread.php?t=711957
    I was told to treat this as F1 = F2 and the displacements are equal.
    I am struggling to convince myself that F(total) = F1=F2
    any help gratefully received

    In the parrallel case I can see how the displacement is the same but again I am confused by the forces.
    I guess I need a couple of spring balances
