Greenpower Car Roll Maths - Chipping Sodbury School

Terry Barnaby - Version 1.0 - 2010-09-04 - Information and Help

This is an interactive, Greenpower car rolling angle estimator. It uses the basic mathmatics outlined in the Car Stability document to estimate the rolling angle and stability factor of a Greenpower car from some core figures. It could be useful to estimate the stability of a cars design before it is built.

To use enter the parameters for your car in the form below and click on the 'Calculate' button. Some info is available on the following link:
