Another shop owner asked me a question as to if I knew a 'rule of thumb' for when a beam had displaced "too much" as a means of determining if over stressed in application.
I didn't as I usually run calculators for load case, beam type and material ME or just look at tables to determine beam size.
But.... he sent the following rule of thumb he found:
https://www.raeng.org.uk/publications/other/15-beam-deflection
Deflection Calculator for Square Tubing
What is the deal?
Rule of thumb a good field check but why get there- It seems the beam can be calculated before placed to meet loads.
The specific application was a queer one where the load case had surge load and twisting moments on beam so......
My rule of thumb in cases like this is to overbuild while relying on examples present for how this sort of widget is generally done.
Thanks
