I need to build a wall mounted table/desk. I've done my calculation (full stress analysis) and I've moved all forces to the mounting points but now I'm stuck because I don't know how much would those screws handle.
Well I do know how much would the screw handle but I don't know how much would the wall actually handle, i.e., the structure could fail because the screw may break the wall (just a couple of centimeters around it) then it all fails.
Another good point is that I've seen weak structures (in my POV) that handle so much weight (more than what I'm going to do) with fewer mounting points but I'm too afraid that my first table falls off.
Any advice? Any possible close structure out there that I could find useful that have really good factor of safety (around 3-4)?
About the design: it's simple rectangle of 150cm x 50cm and could be mounted with 3-5 screws to a corner.
