My name is Wouter van Zoggel. I'm a mechanical design engineer from the Netherlands, and over the years I kept running into the same problem on the job: the information or tool I needed existed somewhere, but finding it and then trusting the numbers it gave me took longer than just doing the calculation by hand. That's not even counting the tools that charge for the functionality you actually need.
So I started building my own reference material and calculators, from formula-based (and later FEA-based) beam analysis to ISO fit and tolerance tools, and eventually decided to put all of it in one place. Free to use, for anyone who needs it. Zengineering exists to spare other engineers that same searching and second-guessing, with tools and articles built the way I wish they'd existed when I needed them.
