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
Thanks in advance
