This calculator was first published as "VibeSD" Ovepressure section on the Apple iOS App Store as a native iPhone and iPad app in 2010. The publisher was Chin-Apse Pty. Ltd. This is app was something of great use to many people. It is a simple calculator of the Scaled Distance Vibration formula in AS2187.2 Appendix J of the Australian Standards. Modern browsers support HTML and CSS better now, as such the app that died on the Apple Store can now live again. Created code is in HTML/JS/CSS. Thank you. Brent Buffham © 2021.
