Hello, I'm Roller26. I wanted to let you know that one or more of your recent contributions to Mechanical engineering have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. Roller26 (talk) 10:09, 2 November 2020 (UTC)
