Hi all, I'm trying to design an arch for a project (will be about 4" long). This arch will be experiencing a load on its vertex, and I need to make sure that the arch will not deform very much. What is a good way to model the stiffness of an arch like this? As far as I know, there is no fundamental solid mechanics equations that I can use for this, and I don't know how to use any finite elements software very well. Any tips on how to model this? Thanks. Edit: Link to sketch of arch. I'm looking for the simplest first-order estimate that would be more accurate than modeling it as just a square simply supported beam.
