free body diagram of bicycle and basic physics calculations

$15-25 USD / hour

I'm looking for a mechanical engineer to draw a free body diagram of a bicycle + rider where the center of mass is known, and to show forces during sudden deceleration that might tip the bike+rider forward into an end-over crash. Known quantities are: total mass of bike+rider, tire radius, wheelbase (distance between front and rear axles), and COG relative to (above and behind) the front axle (or front tire contact-point with the ground). The bike tips forward rotating around the front-tire/ground contact point. Derive formula to calculate maximum deceleration without tipping. I've actually already done the calculations, I just need someone to confirm/verify my results. Getting a 3D animation to show the results in an app would be a plus, but not necessary..

Hello. I'm mechanical engineer with extensive experience in static/dynamic analysis of mechanical system. Because your problem is about planar motion, the free body diagram could be drawn easily and then it can be solved without any challenge. Also I can simulate and animate it using dynamics simulation software (such as ADAMS, WorkingModel4D, ...) if you want. Please message me so we can discuss in more detail. Thanks.
