I am doing some calculations to optimize the power to weight ratio and gearing of a RWD car. I have torque charts and can calculate the force put to the track by each wheel and the static frictional force by the track on each wheel. I am trying to determine what the minimum speed is for the car to be moving before the car is no longer able to spin its tires (overcome static friction), and repeat this process for each gear. Any ideas on how to approach this problem??
