My brother in law would agree with this, he is building an open source project for collecting all of the analysis that civil and structural engineers have to do on every project into a single repository where people can share and augment the calculations. (think if it as github for civil and structural engineers)
I would love to see that as well. I have a project with similar goals (posted above). I would like for users to be able to simply call built in functions to do the normal tedious stuff like stress in rods, beams, etc.
