= (B2^2) / (127 * C2) - E2 (adopted e):

= IF( F2 <= D2, "OK", "e_max insufficient – increase radius or reduce speed" ) (minimum radius for given speed and e_max): superelevation calculation excel sheet

[ e_required = \fracV^2127 \cdot R - f ] = (B2^2) / (127 * C2) - E2

[ e + f = \fracV^2g \cdot R ]
