Spring stiffness calculation - Curved beam

[Vasan]

Homework Statement

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.

I don't know where to start. that is the problem.

The Castigliano theorem ??

really i don't know ! Please help

gosh, that was nearly three weeks ago!

ok, what inputs have you been given …

what exactly is the question? ​

 

[Vasan]

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?

 

[Vasan]

The shape in discussion is the curved beam.

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