Hello, I'm Tobi 406. I wanted to let you know that one or more of your recent contributions to Structural engineering have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Teahouse. Thanks. Tobi 406 (talk) 22:50, 28 April 2020 (UTC)
