    Calculate tilt stiffness

    Folks,

    See attached. I wish to calculate the tilt stiffness as a function of some linear stiffness.

    My attempt is on the RHS of FBD and there is somebody elses attempt on the LHS. I am not sure if it is right.
    I have 2 queries

    1) My attempt on the RHS I wrote the expression of f in terms of linear stiffness (data of which I have lets say 100N/mm). How do I get the actual force? Ie, I am not sure with moment arm to multiply this stiffness value by?

    2) How to write the expression as a function of the angle?

    Thanks
