Homework Statement
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 x2 and x1, I need to find the radius of curvature R so as to find the bending stress on it.
Homework Equations
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.
