How Do You Calculate the Diameter of a Steel Rod for Furniture to Ensure Safety?

[Charles Dean]

Hello I am looking for help with the following:

I am designing a piece of furniture where most of the person's weight will be taken on a metal (steel) rod resting on a wooden batten. I need to calculate the diameter of rod needed to ensure it is safe to sit on. As a chemical engineer I have looked at things like creep strength before, but this is more of a mechanical / structural engineering problem.

Can anyone assist with this?

Welcome to the PF.

Sounds like the design has some problems. Why just a single rod? That doesn't sound very strong. Can you post a sketch?
