# Homework Help: Radius Of Curvature On A Beam

Hey, hopefully this is a suitable forum to put this in! I've been having a bit of trouble trying to find an example to learn from about finding the raidus of curvature in a simply supported beam.

I've got a point loads and a UDL to take into account and seem to find it near impossible to find any examples where the two are combined.

If it helps the question is as follows:

1. A simply supported beam of length 6m supports a vertical point load of 45kN a distance of 4m from one end. If the maximum allowable bending stress is 120MPa:

If the beam has a young's modulus of 200GPa calculate the radius of curvature.

Any information you might need just ask!

Thanks!!

Edit: Read a sticky and you want my own attempt?

Well I would show you what I've done but im that stuck that i dont have anything!!
I'm just trying to get hold of some useful info to get started

Is it supported from both sides?

Hey, thanks for getting back to me.

Yes the beam is supported from both sides.
