Spring stiffness calculation - Curved beam

  1. May 3, 2012 #1
    1. The problem statement, all variables and given/known data

    I'm unable to calculate the stiffness of the spring.

    Once, i get the stiffness i'd like to calculate the load required for the defined deflection.

    2. Relevant equations

    3. The attempt at a solution

    gosh, that was nearly three weeks ago! :smile:

    ok, what inputs have you been given …

    what exactly is the question? :confused:

    Problem statement - For the spring structure shown in the figure, i need to calculate the spring stiffness.

    Input:

    1. All dimensions
    2. Material Spec

    Let me know if i need to be more clear

    what shape was it to start with?

    what does the arrow mean? :confused:

    The shape in discussion is the curved beam.

    The arrow points at the location where the curved beam is going to deflect.
