Calculating size of beam
After extensive searching on the net until I'm now blue in the face, I need a pointer.
Where can I find simple to understand formulas for load bearing in beams etc (doesn't have to be wood specifically).
I know my load (force).
I know the distance from the fulcrum (moment).
I know the tensile and compressive strength of my material (MoR and MoE).
What I want to calculate is how thick my beam needs to be using the above info.
Should be a simple thing, one thinks. And I used to study this in engineering school, but I've forgotten all and have none of the books left. And as I said, I can't seem to find any info on the net after extensive searching.
Even a straight forward construction formula for house construction with cantilevered beams would do. You have a beam, you load it at the end with this much = how thick does the beam have to be?
Please help. Thanks.
