Hi hope someone here can help me or at least guide me to a sensible approach to calculating this problem I have. I need to calculate a Ravigneaux Gear I'm aiming to get 4 gears + reverse with the following ratios: 1st gear: 3.00 ratio 2nd gear: 1.67 ratio 3rd gear: 1.00 ratio 4th gear: 0.75 ratio Reverse gear: (-3.00) ratio. I tried using the formulas from this page: https://www.mathworks.com/help/physmod/sdl/ref/ravigneauxgear.html but since it is based on radius and not teeth count I'm getting really confused. Anyone has experience with it and can help with a "best practice" for how to approach this issue? Thanks!
