I’m building a coffee table. It is a laminated slab (very strong – think workbench lamination) and I’m going to attach some legs on an angle (eg. 85 degrees). I’m wondering how strong the attachment to the apron needs to be. I tried thinking about the leg as a simple lever but I’m not sure that it is as basic as that. Eg. A leg set at 45 degrees is weaker than a leg (in my mind) than one set at 85 degrees. This suggests to me that this isn’t just an issue of leverage with the joint unaffected by anything other than simple leverage.
So, what is going on and how are the forces interacting? Anybody? Or is it a simple lever?
My thoughts at the moment are that it is obviously a lever but leg is some how anchoring to the floor more solidly with a 85 degree leg than a 45 degree leg through friction. But, I really don’t know.
