I'm trying to calculate the maximum acceleration a car can achieve with the current gear ratio. I am ignoring drag forces and friction to keep it simple.
I'm doing this by:
- calculating the torque on the wheels: $T_e/G$ (engine torque / Gear ratio)
- Calculate the Force exerted on the ground:
T_w/r(wheel torque / wheel radius)
- then finding the acceleration using $F=ma$
However acceleration values are too small. Is there something wrong with my reasoning?
My car's engine Torque is 500Nm, gear ratios: [2.97,2.08,1,0.86,0.56], car's mass = 2500Kg
