I assume there's some simple link to give me to answer this, but I don't know the terminology for it and so haven't been able to solve this.
The use case it to avoid having my TV put divots into my IKEA KALLAX.
Here's what my intuition tells me:
- The best shape to distribute the weight is a conical frustum, with the larger circle on the KALLAX, and the TV legs sitting on the smaller one.
- The frustum should have increasing density as its diameter increases. (The density at the bottom should be high to "avoid bending", and low at the top to minimize added weight.)
Are the intuitions correct? I have the sense that a dense substance would distribute weight much better than a less dense one, but why?
My current solution is to use dense foam, which is an incredibly crude approximation of the frustum I'm talking about. How can I tell if it's useful?
Again, my intuition is telling me that there's a falloff curve such that, while nowhere along the foam, is the dispersed weight going to be zero, there's going to be a threshold such that there's no point in having the foam be as wide as it is without trimming.
