(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have a graph of y=lg(x) which is supposed to mimic the curvature of a beam, or I can use y =√x to be more precise. But in essence between two points x_{2}and x_{1}, I need to find the radius of curvature R so as to find the bending stress on it.

2. Relevant equations

3. The attempt at a solution

I don't know if it is as simple as taking the arc length and dividing by π or something. Any help would be fine.

Or could I use

E/R = σ/y

and use σ as the yield stress and get R from there, though that is assuming that it is a straight beam.
