Another good one: XCalcs. It is very powerful when you register.

Those who use Mathcad can subscribe to built-in libraries (there are lots). I find them but useful and fun learning tools. They still turn up in engineering reports that I receive and review. Getting the libraries for older versions of Mathcad can be tricky. If only you could find someone on the internet with a copy…

I haven’t followed this blog because it’s more for structural engineers, but I have seen Newton Excel Bach recommended many times: https://newtonexcelbach.com/

Medeek is another structural design website with calculators (and very nice graphics):

Richard Abbott has aerospace covered at https://www.abbottaerospace.com/ with a huge library of reference material and detailed calculation spreadsheets that you can download and use as you like.
